Hi folks. My exhaust has been lightly blowing for a bit now. Got out of the car today and its got quite a bit worse. Something needs to be done. As you look at the car side-on the hole is right on a bracket roughly in line with the door handles. It's a 172 with the original exhaust at the moment. What are my options from here? A weld seems out of the question. Do I need a new 'cat back' exhaust? I've read a bit about yozza etc but I don't want anything too loud. Thanks for any help.
