I have full tube headers H pipe and two chamber 40 series flows. My exhaust is very loud and i have this rattle that is very annoying. At about 2500-2550rpm its like a metalic sound that kind of sounds like its coming from the trunk or from that panel that the rear speaker go on. I have installed a layer of insulation between the gas tank and floor board and it helped with allot of the little ones but I cant get rid of this loud one! Is there anywhere that is common on these things that rattles? Its a 68. thanks!
