The 1966 GTO came equipped with one exhaust system only. Both the manual transmission and automatic cars came with 2′ head pipes and 2 1/4″¬†tail pipes. The mufflers were unequal length on these cars and the tail pipes made use of a resonator with a 2″ outlet and a double angle cut. Stainless steel extensions were an option. Our reproduction exhaust system comes with the correct head pipes with correct flanges, correct unequal length mufflers, correct tail pipes and yes even the correct resonators once again available only from Gardner. SS tips are available as well as a concourse show package¬†for the customer who wants their system to be a little more real than real.

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