in messing around today with my blk car ,i found that i cut a ton of resonance out of the car by extending the tips after the mufflers 4 in beyond the rear valance . i could believe how much quieter it5 got inside the car, some may not like that look and i totally understand ,butr my old 57 yr old ears just needed some peace and i dint want to give up the performance gains that my dr gas exhaust had given me , by the way its a 21/2in exhaust with an xpipe . the idea came from a muffler guy who is spending the week with us . he also thought that if we cut a resonator in half and gut it then cut openingsso that it fit over the x pipe fill it with steel wool that it might really also quiet things down . he says the resonance comes from in part due to the pipes vibrating at a certain rpms.dont know if hes right but it kinda makes some sence , and what the heck i thought its worth a try . .hope every one has a great t day
