hey everyone, doing some exhaust work.....removed cat and rez and installed flowmaster 40's, but the sound is very nasty (not good nasty) above 2000 rpm. everything is tight and there are no leaks....so what's up? thinking about either putting rez back on or putting cheap cat (magnaflow universal). read lots of info about other peoples tries at the sound...any more expert advice out there?
