i'm lookin at replacing my magnapack catpack on my 04 gt. i'm running a stock h right now but am replacing it with an MRT catted h. i'm looking at buying a couple stingers and having them welded in with the MRT bc i think it sounds pretty good unless i can find someone running this setup with magnapacks. what do you guys think? right now borla stingers run 190 a muffler!
