Still have a bit of an issue with the length of the pipes behind the bumper, not excessively long, but just long enough to make you go "Hmmmmmm", but word has it [from my son - who is into drifting and had a similar setup on his S-14] that due to the way heat is handled by the stainless steel system, the pipes need to be a bit longer so they don't cook the rear bumper opening. He also mentioned that I don't have any tools sharp/good enough to cut stainless steel cleanly - any input would be appreciated in this area 
Still a great system, would purchase again, sound turns heads but does get the neighbors dog upset |
No matter how you do it all metal is hard to cut cleanly - that why you have various types of grinders. Stainless steel is slightly harder than carbon steel due to its higher chromium content, but it isn't kryptonite.
Scribe a line around the circumference of the pipe and put some masking tape where you want to cut it. Use a cut off wheel to shorten the pipes and make a nice straight edge, use a wheel grinder to smooth the pipe face and then use a die grinder to deburr what's left on the inside of the pipe. If you haven't done it before, you might want a professional.
Of course, after the Audi Super Bowl commercial, I hear those Germans are pretty tough on people environmentally speaking - grinding does cause tiny metal fragments in the air. The F in fragment looks kind’a like a P, and P rhymes T and that spells trouble in
