The 1969 Grand Prix HO cars came with 2 1/4″ head pipes and 2 1/4″ tail pipes. These cars are very rare and it took us 20 years to come up with original pipes. Our Grand Prix exhaust system has been reproduced from our original pipes and comes with correct head pipes, correct flanges correct mufflers, correct tail pipes, gm clamps, reproduction muffler and tail hangers, installation instructions, diagrams and sealant. A concourse show package is available  for the person when original is not good enough.

Ask about our Turbo Mufflers for those who want the system to look original but just have to have a little more noise!
