I got a killer deal on a o/r UPR x pipe..already had 40 series flows. Installed the x and mils...now my flows sound like cherry bomb glasspacks!
I had a MAC o/r H with 40 flows on my 99gt, sounded great! I'm not digging the x-pipe sound..but a PITA to swap the thing for a H. Is it just the brand of X pipe? Sounds ok at idle, just when it winds up, the glasspack sound is driving me nuts!
