My bro just got the regular borla cat back and a magnaflow catted x pipe installed. His exhaust tips dont line up. The passanger exhaust tip sticks out 2 or 3 inches farther past the rear bumper cut outs than the drivers side exhaust tip. The installer said its just like that because the x pipe's for mustangs arent even. He said that one side is longer than the other so therefore the exhaust tips are going to be uneven. Ive never heard of this before. Can this be true or did the installer screw up something?
