PostSubject: Header & Catback Option List   Mon Aug 10, 2009 10:02 am

Originally posted by MrBuick (Magnum) on ISSF....


Currently produced Headers for the 94-96 LT1/L99 cars.



*Note, I have added a few Tech articles, and links at the end



*If you have a header, current or discontinued, or info that should be added or corrected, Please PM me!!

This is for Parts reference only. These might not be the cheapest locations to get them. Figure prices as a ball park. Also some offer options such as EGR, AIR, Hook-up pipes, Cats, different coating types.

*Note that some offer the option bolt in, some don't. Prices will be given for both if possible.



Header Parts of interest

*Header gaskets, for the head flange.*


Earls Pressure Masters

http://store.summitracing.com/partdetail.asp?autof ilter=1&part=EAR%2D29DD3BERL&N=700+300501+42948861 22+115&autoview=sku

For Tri-Y, Budget heads, Quad-1's, or Long Tube Headers. Generally regarded as the BEST sealing, and lasting header gasket. There is a metal frame that the header and head sandwich. There is a soft Material "insert" that does the actual sealing. These inserts are replaceable, and the frames can be reused. Might be a good idea to get extra inserts incase you have to remove the headers, and the inserts won't re seal. There are other options, but these are very proven. In many cases, you only have to retighten the header bolts once, with these gaskets. Other gaskets tend to require tightening a few more times after heat cycles. *note that they are a THICK gasket, and might cause header to frame clearances on some headers, such as the Flowtechs. If this happens, you might try a thinner gasket, such as felpro's, mr gasket, percy's, etc.


Earls are not your only options. I will be adding other options as I get the correct part #'s sent to me.



*Header bolts*

Summit Part #

ARP 400-1210

http://store.summitracing.com/partdetail.asp?part= ARP%2D400%2D1210&autoview=sku

Thread Size: 3/8-16 in.
Head Style: External 12-point
Underhead Length (in): 1.000 in.
Underhead Length (mm): 25mm
Fastener Material: Stainless steel
Fastener Finish: Natural


They have 12pt 5/16" heads. More clearance to get socket or box end wrench around. Why buy 12 when for the same price you can get 16 ( just incase you lose one)


Afterburner Hook-up Pipe options from Clear Image Automotive.

http://www.clearimageautomotive.com/...ccessories.htm

Hook-up pipes you can fab to your catback: $100

Custom "X" cross over that bolts directly to the Headers: $250


Export Pipes/Cat delete pipes from Focuztech: $210

http://www.focuztech.com/xcart/produ...rt-style-pipes

Export pipes you can use to delete the cat pipes on your car. goes in place of the manifold to catback pipes, that have the Cats in them.


EGR Delete plates

http://www.clearimageautomotive.com/...ccessories.htm




Headers



*Note that if they are not coated, they are either Raw steel, or painted. If they are painted, the paint tends to burn off. The paint is intended to keep them from rusting in their box. Unless the headers are Stainless, it is strongly urged that you have a coating on them. And even then, there are different grades of stainless. some better than others in terms of retaining heat, and not rusting. The coating does three things. 1. Keeps the heat in the headers, to protect other items under the hood, like wiring, sensors, spark plug wires, A/C lines, etc. 2. Protect the headers from rusting. 3. Potentially help the car produce more power by retaining heat.

*Note: If you buy them painted, you can sand blast the paint off, or do what I did: Use paint stripper to remove the paint, and then use Laquer Thinner on a 100% cotton rag/shop towel to get the last bits off. I found that the Laquer thinner worked better, and faster than the paint stripper, but I went thru quite a few rags, as they got over satuated, and wouldn't remove much more. Once they are Bare steel or If you purchase them Raw, you could always spray them with a Ceramic Enhanced Header paint in a rattle can(spray paint), made by VHT or Dupli-color. which you can get at Meijers, Autozone, etc.

I know of a couple guys who have done this, and not had under hood heat issues. There was even an artilce in Car Craft Magizine, about them doing this to a set of 49100 flowtechs, to get a cheap effective header coating.


There are different types of headers, for different situations. Some locations require your headers to be C.A.R.B. Emissions Legal. Some retain the factory Cat pipes, and Cats in the stock location, and some bolt right to the factory cat pipes. Some require custom pipes to bolt to the factory Catback, and Some offer it as an option, and some offer high flow cats as a bolt in option.

There are also different headers from a performance standpoint, such as shorty's, mid length, long tube, in either a Tri-Y, or 4-1 setup.

It is generally accepted that long tubes are the way to go for the most performance, and that the only reason to use shorties is if your emissions test requires it, or you just can't bring yourself to use a non bolt-in setup, an can't afford the lng tubes that offer true bolt in. It is also generally Accepted that Tri-Y's will make the most power until around 5000-5500 RPM, and then past that 4-1 headers will make more power.




--------------------------------------------------------------------------------

Headers





Summit Performance Headers: $90

http://www.summitracing.com/parts/SUM-G9001/

Painted, check next listed. These look like JUST like the black jack headers.


Summit Performance Headers, Coated: $190

http://www.summitracing.com/parts/SUM-G9001-9/

Long Tube, 1 5/8", 3" collector, steel, coated, require custom hook-up pipes to the factory catback (See Note), No O2 sensor bungs. I'm 99% sure these are the same as dynomax's 85001/86001's. There was a guy who does many LT1 builds, claiming they will fit. I have Sucessfully installed a set of these. I am still not 100% done. Link below.



Dynomax Black Jack headers: $130

http://www.summitracing.com/parts/WLK-85001/

Painted, check next listed.


Dynomax Headers, Coated: $330

http://www.summitracing.com/parts/WLK-86001/

Long Tube, 1 5/8", 3" collector, steel, coated, require custom hook-up pipes to the factory catback (See Note), No O2 sensor bungs, Minor fitment issues on some cars. Check the Summit Headers for an install thread for these(pretty sure they are the same!)


Flowtech Afterburner Headers: $190

http://www.summitracing.com/parts/BIG-49100FLT/

Painted. Check next listing.


Flowtech Afterburner Headers, coated: $340

http://www.summitracing.com/parts/BIG-49100-1FLT/

Long Tube, 1 5/8", 3" collector, steel, coated, require custom hook-up pipes to the factory catback (See Note), No O2 sensor bungs, unless purchased from Jet Hot, Minor fitment issues on some cars. Sometimes hits the passengers side frame rail, which could require minor grinding of the weld bead area. Many guys have used these are a cheap alternative to the $$$ headers. I currently have a set on my 96 Caprice, and they fit decent. they are extremely close to the passenger side frame rail.

*Note: Clear Image Auto now offers Custom hook-up pipes to the factory catback. But they do require some Fabrication. They also offer a Custom "X" Cross over that bolts directly to them. See parts of interest.


Headman Elite Headers, coated: $360

http://www.summitracing.com/parts/HED-68298/

Long Tube, 1 5/8", 3" collector, steel, coated, require custom hook-up pipes to the factory catback, No O2 sensor bungs. The first tube on each side goes UP & over, on these, instead of UNDER and over on most other cheaper headers. This suggests they might clear the A/C on the pass side. There is a member running these, but it was on a 91-93, which can un-bolt the frame braces. He said one side cleared, and the other was very close. I am waiting on installed pics of them, and might try these myself. It looks like they would clear the frame brace better than the summit/dynomax headers, but I can't be certain. Info to come on these.


Grottyhan Headers: $550

http://www.impalassforum.com/vBullet...d.php?t=223739

Long tube, 1 3/4", 3" collector, steel. These are Grott copy's. They are not exactly the same, but quite close. These can be had coated, I think. You will need some custom made hook-up pipes. I don't have a site, but Mike Harris shared the info in the link above.


BBK Shorty Headers, coated: $500

http://www.summitracing.com/parts/BBK-15950/

Shorty Header, 1 5/8", 2.5" collector, Steel, coated. Bolts to stock catpipes with a piece welded on for both sides.

Clear Image Automotive


Clear Image Automotive Is a Supporting Member Of this Forum. Without them, we wouldn't have so many great offerings still being made. You would have the currently still produced shorty headers, or try and find out of production long tubes. They were the driving force behind having the Tri-Y Headers, and Quad-1 Headers Designed, and produced. They Continue to offer new products for the Impala SS, and B-body community.

*Note: Any Header CIA produces, can also be special ordered to fit the LO3 & LO5 engines(91-93 cars).



CIA Budget Headers: $275

CIA Budget Headers, coated: $430

http://www.clearimageautomotive.com/budget%20heade rs.htm

Mid Length, 1 5/8", 3" collector, steel, Raw Steel unless coated. You have a # of options, such as EGR, & AIR fittings, 3-bolt flange full polish of the coating. Hook-up pipes, to the factory Catback: $145. with dumps for cut outs: $220. With Metallic core converters: $395.

Soon to be discontinued.

http://www.impalassforum.com/vBullet...d.php?t=224554

I bought a set of these, For a ROADMASTER, and they are built very tough. BUT, I had the same clearance issue at the passengers side frame rail, usings the earls gaskets. I also had a problem with them rubbing the steering shaft with the earls gaskets. I was told the fitman on a caprice/impala is better, and a Fleetwood has MUCH more room. The Fleetwood is what I originally bought them for. But it took me 6 months to get them, and I totaled the car a few days later. Since then, CIA's turn around on headers has improved. Link to the RMS fitment issues.

http://www.impalassforum.com/vBullet...d.php?t=143018


CIA Tri-Y Headers: $575

CIA Tri-Y Headers, coated: $795

Check the site for other prices, and packages.

I used a coated set of these on my Roadmaster, after the Budgets didn't fit. The fitment is much better, in all area's. The budgets required turning them just right, wiggling them, and more thinking to get them in there from the top. These fall right into place, and the only mod needed is to bend the Oil dipstick. It took me about an hour to fully remove them, and the hook up pipes when I took them off. Install took me about 1.5-2 hours, because I took my time.


CIA GEN II Tri-Y Headers: $745

CIA GEN II Tri-Y Headers, coated: $970

--------------------------------------------------------------------------------

Catbacks for the 94-96 LT1/L99 Sedans.



These might not be the cheapest prices, or only place to get them. The over the axle pipes can be modded to work on wagons, but will not bolt-in as-is.

*Note: Fleetwood owners. Any Impala SS system can be made to work. All you need to do is have about 6"-12" of pipe added to the cat to muffler pipes.

*Note: Parts for a 91-93 cars custom catback are included in "Parts of interest". Check the "215" catback note for details. Also, Tail pipe kits for the wagon are also included. If you wish to build your own custom system, or are on a very tight Budget, check the "Parts of Interest" for some cheaper options.



Complete bolt-in Catback Exhaust systems



Jeg's Catback: $270

http://www.jegs.com/i/JEGS/555/30410/10002/-1

2.5", Welded turbo mufflers, no resinators, no cross over, steel, stainless tips, clamps, hangers, hardware. This Catback is likely the BEST bargin out there, for acomplete, Ready to install carback. People who have used it, didn't have many, if any complaints about the fitment. Also not many complaints on the sound either. I think the mufflers are made by "heart throbb". Add a universal H, or better yet, an X pipe, and you have about the most cost effective catback. While still not sacrificing much, if any power.

Here is an installation guide from heartthrob

http://www.heartthrobexhaustinc.com/2009496.PDF


Pypes Catback(no mufflers): $380

http://www.summitracing.com/parts/PYE-SGI10/

I had my doubts that the pypes X pipe was Stainless. But having installed one, it IS infact stainless. likely the cheaper 409 grade, but still a bargin! If the entire system is stainless, then that is one GREAT deal. You get an X pipe, and stainless for the cost, WOW!

*Note: The pypes X pipe is a decent fit, but not perfect. You might need to trim the pipes where they enter the X pipe(inlet side), to get the X pipe centered under the car. You also can twist the drivers side pipe to gain more clearance at the trans crossmember, but in doing so, the outlet by the muffler, for the drivers side, drops down some. I found that the Pypes X pipe fits quite a bit better with a Tubular Crossmember(can be purchased from Clear Image, Focuztech, or other places. I think they are made by Bowtie Overdrives) If you check the Parts of interest section, under the pypes X pipe frankenstien catback, there is a link to my install, and pics of the clearance.

2.5", Spintech Pro street or Sportsman XL, "chambered" mufflers - bare, no resinators, Dr Gas X pipe, aluminized steel(Available in Stainless), 30" long "Stealth" stainless tips, clamps, ties to factory hangers, hardware. Pro Streets are Generally considered some of the loudest mufflers out there, also have a very personal sound to them. Likely one of the most used Mufflers on this site, and definatly a favorite of mine, if not number #1.

Spintech systems seam to be very hard to track down to order, or get pictures of. I did notice that you can't interchange a set of Pro Streets where the Sportsmans once were. this is because the ProStreets are not nearly as wide as the Sportsmans/most other mufflers.

*Note! Spintech also offers 3" systems!



Clear Image Auto Catback, 2.5" Pro Streets: $630 - 304 Stainless: $1,050

Parts of Interest, & Build your own Catback parts.








"215" aka Frankenstein Catback: $215+ (realistically $250+)

http://www.impalassforum.com/vBullet...ht=215+catback

There is the link to the ORIGINAL thread. Consists of two, 2.5" Dynomax Intermediate pipes, two, 2.5" Summit turbo mufflers, and two, 2.5" Dynomax over the axle pipes. Then you just get some flanges for the cat to intermediate pipe, clamps, some hangers, Some extension pipe to the tips, tips of your choice, and your set. The Length of the dynomax Resonator, and tip is 23.25". So you would need a combination of pipe, and tips to make up that roughly 24", which is 2 feet. The way it is set up, you would have "stealth tips". If you want the Flowmaster style, where the tip is visible along the bottom of the fender, a minor modification might need to be made to bring the pipe outlet a bit lower. You could very easily add a universal H pipe kit. Or have a muffler shop add one.

*Here is a link to the Dynomax Catback parts list. you can see the parts that were "stolen".

http://www.dynomax.com/products/cat_...upons/5034.gif

Part numbers:

WLK-45688 - 2.5" driver cat to muffler pipe
WLK-45687 - 2.5" pass cat to muffler pipe
WLK-54017 - 2.5" driver over the axle pipe
WLK-54016 - 2.5" pass over the axle pipe

SUM-630225 - 2.5" Summit Turbo Mufflers, Offset in, Offset out

*Note: You can always forget the over the axle pipes, and just have turn downs on the ends of the mufflers. Some guys do it to save weight, make it louder, save money, or to change the tone of the exhaust. Removing the over the axle pipes seams to make the tone a bit deeper, louder, and remove a bit of the snap to the exhaust. But on the flip side, if the mufflers ever thought of producing drone(that buzz like humming while you yawn), you will know it without the tail pipes. When you don't get the exhaust out from under the car, it tends to bounce back into the cabin.

*Note: For 91-93 Sedans, you can use the Passengers side pipes, a single muffler, and have a very nice single 2.5" catback. Or, you can run any LT1 catback, so long as you run some custom pipes from the manifolds/headers to the catback. You will need to modify the trans cross member by either cutting out a section, and welding a plate on the top, getting a tubular cross member(available from Clear Image Auto, among other places), or getting a 94-96 cross member, and mod the bolt holes to fit the 91-93 frame.


Build your own Catback, Muffler's: $40-$240 a pair

http://store.summitracing.com/egnsea...splayPrice%7C0

Here are some of your other 2.5" muffler options. Nearly any one of them will work with the four "215" catback pipe, so long as the offset is not on the same side, 2.5" offset in, offset out. Some pipe might need to be trimmed off the cat to muffler pipes, if you have a larger case muffler(longer), such as the long case dynomax super turbo's.


Spintech Mufflers: $85-$120 each

http://www.spintechmufflers.com/spin...ntechindex.asp

order of loudest to quietest. 2.5", offset in, offset out.

Pro Shoot out's
6334 - Pro Street's
3334 - Sportsman Street's
3334XL - Sportsman Street XL's


Universal H pipe kit, 2.5": $35

http://store.summitracing.com/partde...5&autoview=sku

2.5", H pipe, 2 center sections to pipe from, aluminized steel, clamps. This looks like a great kit for add an H pipe to a 2.5" catback you may already have, such as the Hooker Catback, or the "215" catback. I have used this kit before, and it works pretty good. An H pipe isn't as good as an X from a performance standpoint, but it's much better than no cross over. It will also even out the exhaust tone, and quiet it down slightly. A great idea if you are on a budget and want a cross over. For about $50 more tho, you could step up to the X pipe kit for an existing catback, or a pypes X pipe if you are still piecing a catback together.


Universal X pipe kit, 2.5": $85

http://store.summitracing.com/partde...art=SUM-642125

2.5", X pipe, 4 legs from the X, aluminized steel, clamps. This looks like a great kit for adding an X pipe to a 2.5" catback that you may already have, such as the Hooker Catback. Now if you are just piecing your catback together, such as a "215" catback, you would be better off to go with the Pypes Frankenstein Catback. Reason being, the 2 dynomax pipes, plus the universal X pipe kit ends up being about the same cost as Buying the Pypes X Pipe! So you would be saving yourself headaches, and time by using the pypes X pipe. An X pipe, from a performance stand point will boost power over an H, and quite a bit over no cross over. It will even out the tone, and quiet it down some. A bit more than an H will.


Pypes X pipe: $160

http://store.summitracing.com/partde...5&autoview=sku

This the the cat to muffler section used on the Pypes Catback. 2.5", X pipe, aluminized steel.


Pypes X pipe Frankenstein Catback: $300+

Pypes X pipe from above, 2.5". Bolts directly to the Cat's. You can use your muffler of choice from the above options, 2.5" Offset in, Offset out, along with the Dynomax WLK-54017 - 2.5" driver over the axle pipe, & WLK-54016 - 2.5" pass over the axle pipe, extension pipe and tips of your choice. Check the "215" catback for details on extension & tip length. I feel that personally, this is the best budget performance option. You get an X pipe, mufflers of your choice, and tips off your choice.

*Note: check the Notes under the "215" catback

*Note: Using the Spintech Prostreets will cause some problems with this setup, because the spintechs are not as wide. I Did this myself, and found a solution.

Clear Image Auto "True Flow Balance Pipe". "X" pipe: $265

http://www.clearimageautomotive.com/X-pipes.htm

*NOTE* This is not actually an X pipe. It is a different design that works similar to an X pipe, but does not physically take the X shape.

2.5" bolt in cross over. bolts to the factory cat pipes, and then you fit it to your mufflers of choice. Aluminized steel, available in stainless.


Wagon Tail Pipe kit: $205+

http://www.clearimageautomotive.com/...%20exhaust.htm

2.5", aluminized steel, stainless tips. Check the site for more info.




Parts for the Stock Exhaust

If you are on a very tight budget, just want to change the sound or can live with roughly 75% of the gains(power, and sound) over a full catback. Here are some options for you.




Here are some pictures of the stock exhaust pipes. The first picture is the drivers side cat to muffler pipe. Click back to look at the other pictures

https://s113.photobucket.com/albums/n...t=DSCF0015.jpg





*Note: The stock pipes are 2.25" from the manifolds to the mufflers, and then 2" from the rear of the muffler to the bumper.





Muffler Delete




Parts needed for *one side*. Use the stock mufflers are a template for the length, and inlet/outlet placement.




Details coming after I check my setup




Removing the mufflers, and adding "straight pipe" is about the cheapest way to change the sound, and add some performance. You might be surprised how quiet at idle it is with this mod. It is rather loud at WOT, but overall sounds is very decent. The small 2" over the axle pipes, and resonators help keep it in check. Adding headers, and removing the Cats makes it very loud.





Muffler Replacement




http://store.summitracing.com/egnsea...splayPrice%7C0




Here are some stock exhaust, muffler replacements. Nearly any one of them will work with the stock catback pipes, so long as the offset is not off to the same side, and the inlet and outlet are not on the same side. 2.25", offset in, offset out. They will require a 2.25 OD to 2" ID adapter, to go from the outlet of the muffler, to the over the axle pipes. The mufflers may require a bit of pipe to make up the difference in length, compared to the stock mufflers, which are rather long. A 2.25" "tail pipe"(for each side) from say autozone can be trimmed to make up the difference. 2.5", offset in, and offset out will work, you will just need a 2.25" ID to 2.5" OD adapter, for the inlet of the muffler. which may, or may not make up the difference in length compared to the stock mufflers. For the outlet you will need a 2.5" OD to 2" ID adapter. Reason for using 2.5" mufflers, would be if you planed on doing a 2.5" catback in the future, and wanted to use those mufflers.
