Well i got some pacesetter mids, love em. Fit gr8, easy install, blah blah blah. Anyways the driver side collector seal mates up fine no leaks. Im using percys collector gaskets btw, well on the driver side I got it as tight as i could get it, then i even torqued it down will up on a lift with the car running to see if i could quiet it down... Well no luck, can I double up on the collector gaskets??? Like use one aluminum 1 and 1 mr. ultra seal???

 

you can try sandwiching the aluminum gasket between 2 felpro gaskets, I'd give that a shot see if it helps.
