Ok so i live in a apartment and have no jack or jack stands and my exhaust is making a squeaking sound and its getting louder and super annoying its at where the down pipe meets the mid pipe if it helps at all i recently replaced the down pipe and hardware so may be just loose or bad donut gasket so if anyone is willing to help that would be great just give me a shout thanks................
Some DPs have a bracket coming off of them near the O2 bung. Maybe that's loose? Not sure if you'd be able to get under there without a jack though... (Edit: I'm about 2 hours away from you so hopefully you can find closer help lol)
