the only thing i think that will be hard to bend/ make is the real curvy section over the rear axle.. am i right?

Expert, not really Dr. Diesel  :lol: , a novice at most.

I sent you a PM but I didn't answer all your questions.

I made the exhaust using 2.5" 90 degree mandrel bent elbows and 2.5"  tubing. These were all .065" wall stainless steel. I cut the elbows into 45 degree bends which I used on nearly all the curves. The pictures I'm going to send you should give you an idea of what the downpipe looks like. The curvy section over the rear axle was somewhat difficult to line up, including the hangers. I didn't get it right though. Between ~1100-1150 rpm the exhaust vibrates enough to hit the body to make an annoying rattle. Other than that it came out pretty good and I picked up about 2 mpg in the process.

I too am interested on how you made your down pipe and the rest of the system. I am trying to make a system for my 1.6TD 85 Jetta and i am not having very good luck with it. if you could PM me or sent the pics to me at [email protected] that would be soooooo sweet.
Thank you for all the help!!!! JVG
