I didn't use the CMC units cause I wanted the long-tube headers with the collector visible on the outside. I used the headers from Bethania, but was not too happy with them. There were some fitment issues, and I had to have the flange surface milled to solve some major leaks. When I called, they weren't too helpful -- actually sounded irate. But that was some years back, so things may have changed now.

A couple years ago, I had Miami Racing custom-build me a set of sidepipes to my specs and they did an excellent job! Not sure if they'll do anything remotely, but the point of this is that there are good custom-exhaust shops out there and if I had to do it again, I would definitely choose that route and have my headers/pipes built to suit the motor and the specific installation.

Talk to people like Headers By Ed, Burns Stainless, Stainless Specialties, etc for sources.
