14 months ago I purchased and installed a catback exhaust from a DC dealer online as well as the header from RoadRace. Although I live in the NE, my parking is in a heat controled garage.
Two weeks ago the stainless extention that comes off the back of the muffler just must have fallen off...taking the silencer with it. This means that I'm not passing inspection any time soon. The ring was supposed to be welded all the way around, but apparantly not so good...as well as some other spots on the exhaust.
Here is the problem..... The exhaust is supposed to have a 2 year warranty which seems not to matter....cause even when they randomly get back to me via email they pretty much are telling me to buy the short piece of tube and have it welded on my self.

Just wanted to share this story for those people in the market for catbacks. Mine might be rare, but still super annoying.
