So I've been dealing with this problem for awhile on my Saturn. Everything I've done seems to only work temporarily. The exhaust is hitting over the back suspension. There isn't a lot of room or anywhere to really strap it up. The muffler hanger is as tight as can be trust me. I about killed myself getting that tight.
what should I do. Its not so bad that it does it all the time it does it once in awhile . Also last night went grocery shopping and had a trunk full of groceries and it rattled bad then. Its not a constant rattle just mostly going slow down my road or something bumpy. I know the problem just not how to fix it. Anty help is appreciated
