This has probably been discussed to death, but does anyone still make exhaust systems for the 91 B Body? I'm not interested in swapping frame crossmembers to use a 94-96 dual, just looking to improve what I have on a car that will never be a show piece, but is too good to scrap.
I'm about to rotate the 94 back into service for my girlfriend to drive, bvecause I don't think the 91 will pass the new emissions Travis County foisted on us, in their infinite wisdom.
Lord, how I hope the 94 will pass. It'll be a long 24 years, otherwise...
Once the 91 goes semi-retired, I can start tweaking a bit. Get a new exhaust, new cylinder heads, upgrade the TBI, with a new chip and the proper knock sensor and ESC module and a cold air intake.
So, starting with the exhaust, am I better off looking for the 92 police Y-pipe and getting a custom (3"? 2.5"?) job done with the LT1 exhaust manifolds that came from the 94 and a better than stock cat, or is there still a package being manufactured that will do even better?
