Hey its been a long time since i first installed my exhaust, but i recently put in boosted header and rear mm inserts. I think the added vibration is causing my car to "chatter" at around 2.25k rpm reving and about 2.5k rpm in gear. Im sure its some resonant freq crap and is def coming from the rear.

Last weekend i pulled of the rear exhaust to fix another noise but i noticed there is a little bit of free movement between the midpipe and exhaust. Im guessing that movement is causing the clanking noises.

My question is what type of gasket is supposed to be there between midpipe and exhaust, i had nothing in between them. Im pretty sure is a gasket due to the parts avaiable but jsut wondering if it is a donut or more of a flat gasket type thing. THanks
