i think sumthing is wrong with my exhaust....its normally loud cuz i have a 3" thermal, but it just got louder and i hear rattling....and no exhaust coming out the muffler....sumone please respond quickly...

 

what you mean by no exhaust coming out of the muffler? There maybe a leak between the piping, where the gaskets are at. For the rattling part how loud is the rattling? maybe the piping hit the heat shield, or the muffler hitting the back bumper

 

i mean there is nothing coming from the back and its hella loud...like shakes the whole car at IDLE and im guessing the cat and the exhaust pipe just got disconnected....im gonna go get it checked out soon....but i just wanted sum opinions first
