I'm planning on putting new exhaust on my '77 B body A38. The car still has the factory exhaust on it with muffler that have an offset inlet/center outlet. I pulled up a Walker Exhaust schematic which shows the opposite...center inlet/offset outlet. The last time I went to the muffler shop I brought a pair of mufflers that matched what was on the car ('68 Road Runner) and was told they were wrong according to Walker. So I brought the "correct" set of Super Turbo's per what the Walker instructions said for the Road Runner.

I'm just curious if anyone else has one of these cars and what you used for aftermarket exhaust. I plan on going the "stock" route with 2 1/4" piping etc but planned on using Dynomax Super Turbos.

Thanks for any info.
