hm. i never noticed any vibrations in that area when i got my exhaust. i know the muffler sits pretty close to the trunk on the underside, mine does anyways, apexi kinda has a big muffler lol. the only thing i can maybe think of is the hangers are making it touch the bottom of the trunk?

quick question - since you're gutted i figure you might know

just installed my exhaust and got a good amount of vibration rattle in my trunk bay area - some of which im sure is from the lid itself - any other areas i should look at??
