The 1970 1971 GTO Systems were the same for both automatic and manual transmission cars however they did change from 2″ to 2 1/4″ head pipes for the std duty and Ram Air cars. . The rest of the system consisted of 25″ long mufflers and 2 1/4″ tail pipes with a splitter placed on the end for aesthetics. Our systems come reproduced from originals, they come with the correct head pipes with correct flats where applicable, correct flanges, mufflers, muffler hangers, gm style clamps installation instructions, diagrams and sealant. Brackets, bolts and splitters our reproduction¬†tail hangers, and 2 1/2″ strap clamps are available. Ask about our concourse show package¬†when original just is not good enough.

Ask about our turbo mufflers for a little extra roar!
