In 1973  if you stepped up your Firebird order to the super rare Super Duty your head pipes and over axle pipes would have been extra large to others of the day at 2 1/2″ and larger tail pipes than the base Firebird at 2 1/4″. Our Super Duty Firebird Exhaust systems have been reproduced from originals and come with the correct head pipes with correct flats, correct welded on resonators, correct over axle pipes, correct tail pipes with exact original bracket welded on, correct transverse muffler, GM style clamps, installation instructions, diagrams and sealant. Reproduction cast flanges, muffler hangers and tail hangers are available with our systems as well as our reproduction chrome tips. Ask about our concourse show package for those of us who like the restoration to be a little more real than real.
