Building your own intermediate pipe
Building your own intermediate pipe
Has anyone built their own intermediate pipe out of various individual, pre-bent exhaust elbows or are the angles too complex? It looks to me that you could use a 45 degree before the rear axle, a 90 degree over top of the axle then another 90 to turn into the muffler. Maybe it's not worth the hassle but it would open up the possibility of using larger diameter tubing that isn't available in a pre-made I-pipe. Thanks!

for what its worth, Dyno Don makes a 3" intermediate, I just put one in my car and the fit is pretty good for 3" pipe

any exhaust shop can bend you a pipe for cheap. Walker also makes and individually sells a pipe that goes over the rear axle. If you can weld you can always use pie cuts and make it do anything you want.

Yeah, I don't have any shops around here that can do mandrel bends that I know of. I was wanting to doing stainless so that's why I was looking at using pre-bent elbows. I don't know of anyone that makes a stainless I-pipe that you can buy without buying a whole kit.

You don't need a mandrel bend unless your in some dynoed challenge. Bend a 3" and be done with it.
