I installed a BBK O/R H-pipe (BBK1507) and American Thunder C/B. The C/B is fine but the H-pipe wont fit right. It connects good at the Factory headers but hangs too low at the rear where the muffs meet. If I raise it up to where it touches the x-member they still hang too low and drag the ground. The car is NOT lowered but the motor mounts are weak. But is it possible for them to be weak enough for a pipe not to fit?
