Who did you get your exhaust pipe from? Was it just a bunch of bends or was it more of a vehicle specific kit or …?
The exhaust pipe is 2 1/2" stainless steel sanitary tubing scraps that were left over from a job at work. I also got a few 90 bends as well. I cut the stock manifold flanges off of the down tubes that came with the engine and welded them to the stainless tube and welded stainless oxygen bungs that i got from summit to the tube. I just cut and mitered the fittings for the angles i needed and purge welded everything together. It took for ever to do, but it turned out better than expected. I still have to finish up the exit pieces after i get the body back on. I got the stainless Borla mufflers from a place called Street Side Auto for $65.00 a piece! I used the band clamps from them because i was worried that it would be to loud for my tastes, but after a test run of the engine it sound great. I may take the band clamps off and weld them in as well now.
