I figured id ask b4 i go looking under and measuring and trying to figure it out. Does any 1 know the exact parts i need to build my own exhaust. Like how many bends, what degree, how long ect. its for a 88 S4 TII. Im doing 3" piping from the DP and not having a cat. If any 1 can help that has done it b4 or has the knowledge, it be greatly appreciated =) thanks

 

It shouldn't be too hard to figure out by looking at some pics of any stock or aftermarket exhaust system.
