Hey Guys,

I installed this on Saturday. Sounded mint! Drove the car all around over the weekend and then late this afternoon the exhaust note started to sound harsh and awful. I snuck the car home presuming the exhaust bolts had worked themselves loose. (I was envisioning loosing them on the drive home).

Once in the garage I slid underneath. Nothing was really loose. I got 2 full strength turns out of one nut and the others maybe a 1/4 turn.

This helped a bit. But still doesn't sound as clean as the last two days. Vibration also. Could the exhaust gasket be the culprit?

I removed the small black heat shield on the passenger side but not the big silver one where the old muffler was.

Any ideas?
