for the past week my car has sounded like a run down diesel truck. After wondering WTF was up, i noticed a loud, banging, clunking sound coming right my passenger side test pipes.

Went to the shop and lifted the car... there was a small mouse inside my test pipe...

Just kidding, i had a blown gasket. Not sure how it happened, but the blow gasket really changed the sound of the car. The engine sounded off (well the engine sound was changed because the damn clnking was so lound) and the exhaust sounded like it had a piston hitting the wall of the test pipe.

If anyone with an aftermarket exhaust experiences wierd noises, check the gaskets!

Regular vs blown


that is all

Was the noise similar to these clips that I posted on my thread? I've been starting to think my noise could be something on my cats or my headers maybe a like yours a gasket gone bad bought It seems like it would be really tough for an OEM gasket to go bad... I have OEM cats no test pipes so the metal Oem gaskets are in place...
