hey guys i bought the 14" magnaflow muffler and had it installed on my 07 titan and it sounds *****in when just toolin around town but here is my problem when you open her up and floor it, there is this like popping and pinging sound kind of like those old cars you see and they make that loud crappy sounding popping sound out of the exhaust. does anyone know how i can get rid of this. maybe adding a resonated tip i just dont know, but i dont want to quiet it down cause its really not that loud.:flying:
