anyone ever do a 4" single exhause setup?
I have a 4" exhaust I built myself out of stainless steel mandrel bends. The three inch header collectors feed into three inch tubes, then into a Flowmaster Y merge with 4" output. That dumps into a Borla XR1 race muffler with 4" input and output, then ends just before the rear axle. It's loud, but it sounds good. I have a three-inch single over-the axle tube that I can easily install when I'm not racing to make it quieter.
I have a friend with a 95 trans am with long tubes and the 4'' mufflex system with the spintech muffler. It sounds absolutley amazing, i would recomend that system to anybody looking for a real muscular sound!

I never did ask you when you posted pics on FRRAX, but what kind of ground clearance do you have right at the XR1? I'm guessing that's the lowest point on the car?
Mufflex does indeed make a 4" catback.
I ran their single outlet 4" with the Flowmaster muffler, but swapped the muffler for the Dynomax Ultraflow welded muffler. I was worried that the Flowmaster was restrictive.
If you did not go Mufflex, you can look around and go to truck places and buy 4" bends and cobble one together yourself if you have skillz.

a little confused though maybe I am retarded but why is there a mufflex catback system with flowmaster mufflers (or spintech). Isnt mufflex the muffler? I mean you dont get a magnaflow catback with a corsa muffler so I guess I just have no clue. Help a retard out. Thanx.

I 2nd the awesome sound. My friend and I built a 4" exhaust out of mandrels and a 40-Series and such on a 3rd-gen T/A, and it shook the ground idling... I mean, you could feel it in your chest. At 7500 rpm though, it sounded more like it was happy, instead of like it was straining a nut to keep going.
