my wife wanted to drive fast so she broke in early 11,000kms in 6 weeks. Sounds good just got hit from behind today so now need muffler and rear bumper. And yes exhaust sounds mean esspecially at startup. No Droan sound just makes it sound diffrent. Superspint can be better for install crappy brkt's took 3 hrs to line up muffler and pipes just right for 2 of us. Take to shop and have welded because those Italians could have used jb weld to hold clamps on and they would have worked better.I've been contemplating on this upgrade. How many miles did you log before the upgrade? Also, is there anything noticeable with the exhaust sound?
