I know there are a few that have DIYed their exhaust system with mandrel elbows and I'm about to do the same. I'm trying to find how tight of a radius I need to use if I wanna do a 3" cat back system. It seems that a 6" radius is the most easily available. Since the car is not available to me right now I can't do any measuring but I wanna order parts. The car is a 95 200 SE-R w/ stock cat. Help or suggestions? Thanks!

Yes consider getting this prefabbed one. LINK (http://www.sr20deforum.com/showthread.php?s=&threadid=22119) I say this because I just priced the parts for a 2.5 inch mandrel on my b14. It came to 340 for the parts only using Magnaflow stuff. I am getting it done for 325 at a local shop total.
