rear end clunking/exhaust leaks - 80Q

[David]

Interesting. 18 months?! Eek! My CGT still has (parts) of the original OEM system. The rear muffler finally rotted out about a month ago, so I just cut it off and put a piece of pipe in it's place (still has the OEM resonator). Now it sounds like a decent aftermarket system...

Anyhow, the reason I mention it, is that the center muffler appears to be coming apart inside, so it sounds horrible.  Louder than my car has ever been.  Sounds like I have a horrendous exhaust leak.  Kind of like I'm dragging a lawn mower too.
