First up, I have an 89 cherokee. I did a hard 0-90 acceleration today and after doing such, I noticed it was.. louder. I got home and checked it out and it turns out the tail pipe completley broke off the exhaust (looks rusted out). I looked further and apparently the muffler is loose. It's hard to explain but, when it was working, the exhaust goes from each cylinder into a single pipe, this pipe goes down from the engine, then along a straightish line to the muffler. From the muffler, it goes along a straightish line to the tailpipe, and that's it.
However, the exhaust pipe that goes from the engine to the muffler isn't welded or attached to the muffler in any way. In fact, if I took off the attachment that holds the muffler up close to the body, I could take the muffler off, plus all of it's pipe that leads to the tail pipe. The muffler just "sits" on the exhaust pipe that comes from the engine. Is this normal? I wouldn't think so. Did a weld inside the muffler break off? Thanks.
