4 inch exhaust
anyone interested in a 4 inch exhaust off of an 89 iroc, has about 2000 miles on it. spintech muffler, has y pipe for hooker long tube headers that goes into a 4 inch intermediate pipe, and into the spintech muffler and out in dual 3 inch, i have quite a bit invested in this exhaust and just don't need it anymore. probably not going to build a car that need it anymore. i guess i will start at $350 or trade, possibly for a builder ls style engine. will send pics upon request.

Re: 4 inch exhaust
Well I just bought a 4 inch spintech and headman headers so allb I bwould need is pipe. And I'm tired of everyone around here telling me it can't be done or they don't have the pipe or they can't bend it

just updated with some pics, and 91camaroRS, you just looking for the y-pipe? obviosly it can be done, and if you would like i can send you some detailed pics and specs on it, should be easy to have your local muffler shop build, the one here did it.

Re: 4 inch exhaust
I promise it can be done, bending 4" takes special equipment that very few have. I had the same deal, a friend bought a 4" Mufflex kit about 4 years ago and I wanted a similiar set-up but didn't have a grand to drop on it. So, I did what any good fabricator would do. I helped him install his, took some pics, pulled a few measurements, and...One night in my shop, and $300 later I had my own. I even built a crossmember so my 3" Y pipe would tuck really nice. I had a local exhaust shop build my Y pipe it cost $75. so for $375 I was done. and I also used a Hooker Aerochamber muffler with one sided 4" dump, looks sweet..My oponion for the money this set-up is a heck of a deal. Spintech is nice stuff and very expensive, so a free BUMP for a good deal....
