We are looking at putting a dual exhaust sytem on our 71' cutlass S. Bascially we want it to look like it was factory, not like a 442. Who make's a kit for these cars, or do you need them custom built?

 

My best experience has been with the local muffler shop. If you can find one that is trustworthy and they really KNOW what they are doing, you can have almost anything done. You would be looking at exhaust pipes with downtubes behind the rear wheels facing downwards and out slightly, midway between the wheel well and the bumper right? Shouldn't be a problem if you use 2.5" pipe.

 

We want to go from the manifolds back but no headers. Bascially its just the way you said.
