I think something is wrong with my exhaust. I think it's my Xpipe but not sure. It could be the catback but it sound like it's from the xpipe. Today when I was riding home it all the sudden started making a deeper hollower noise with a rattle as well. The noise is very loud when I'm starting in first and second. I'm not sure how to explain it better but it doesn't sound good. Does anybody know what a messed up Xpipe sounds like? I reved it for my wife to hear and she said it sounded like something was scraping. It was on the car when I bought it so it's about 2 years old. Is two years about the life cycle of bassani's? Maybe one of my Cats went? Any help or even speculation is appreciated, I don't know much about exhaust.
