What is the stock inlet and outlet muffler size and layout on a 93 buick roadmaster wagon? Was wanting to put super 44 flowmaster...

You can get adapter pipes for both ends at your local parts store.

Jacking it up to look at it and measure not possible? Even better take it to a muffler shop and tell them what you want.
Not 100% on this but it should be 2 to 2.25" with offset inlet and outlet.

I believe it is offset to opposite sides.

The problem your going to run into if you want to run true duels is the trans mount it's set up for a single exhaust . When I had my 93 I got a later model 94/96 cross member and had a muffler shop fabricate a system for me it wasn't cheap .

Duals are actually easy. I welded a bar on top of the driver's side, and cut the area out under the bar, then used the scrap from the cutout part to cap the ends of the tube. You do not even need to buy another trans crossmember.

Haven't had a chance to get under the car yet. I was only interested in swapping the stock muffler at the moment. But that is good info about the dual exhaust setup.
