I did a search and didn't find an answer to this specifically so here goes.

Can anyone that has removed their resonators describe how big of a difference it made, pros and cons?

I added a pair of Summit Racing's flowmaster knock offs to my Roadmaster. It sounds better but not quite wht I was looking for. Just wondering if removing the resonators would be too much.

I removed mine when I put a Pypes Street Pro Impala system on my RMW, with the exhaust exiting just after the rear wheels. It was too loud imo, and I ended up mating the stock tail pipes (w/resonators) to the Pypes ota pipes. It's still pretty loud, but not obnoxious, and I like it much better. It's not an apples to apples comparison though, as I added the full tail pipes too, and that will make a difference in sound as well.
Pro's- louder
Con's- louder

If I do it I will just remove the resonators and replace with pipe. I'm gonna drive it for a couple of weeks like it is then decide. Thanks for the response!

The resonators just cancel drone; they do not muffle. They are open boxes. If you replace them with straight pipe, you will effectively have a 7 foot long pipe in which standing waves will form and cause godawful drone. Spend some time studying exhaust system theory before you do anything with them.

Then, go to a parking lot and look at the factory exhaust under every single car and truck there. You will find that factory systems nowadays have less than 4' between the muffler and the end of the pipe, and many times less than 18". This is done for a reason.

Currently I have the stock mufflers and over the axle pipes and they run to the back bumper.. Its still quiet.. The system that I had before was 18" Magnaflow mufflers cut and welded OTA pipes and Dynomax race bullets for Resonaters all in 2 1/2 inch mandrel bent pipes. It had a nice sound and had turn downs at the bumper..

I removed the resonator and have (single exhaust) one straight pipe after the axle. Sounds not to bad and doing 70 mph there is no big difference having a resonator or not. Pulling away from a stop is somewhat louder. (IMO)
