Message: I just installed the Gibson swept side catback and now there is a rattling sound that seems to be coming from my catalytic converter when I'm idling. The stock exhaust was a b!tch to get off, and we were tugging at it some before we just cut the thing off, and I'm wondering if we screwed something up by all the tugging or cutting. Is this something that I can easily fix myself, do I need a new cat, are there any recommendations...
thanks
