Members buy a great ride like the G35 and add test pipes and some chicken **** knockoff muffler and expect it to sound good...what are you thinking?? If you want a exhaust system that performs and sounds good too buy a name brand like HKS or Motordyne. Even systems like Stillen and Magnflow will deliver better sound/whp than putting together a half azz system. The Magnflow crossover we installed in our HKS exhaust was to replace the restricted crossover which hopefully no longer exists in later models. Had you done a Search you would have discovered this...Gary

Just wanna thank everyone for bashing me over this stuff

I put it on a lift yesterday and inspected the whole system ... I tapped on the pass. test pipe and it sounded normal... tapped on the drivers side... BAM it sounded like there's either something inside or loose in the the where it meets the mid-pipe. metal on metal action
