1969 GTO Exhaust System

The 1969 GTO Came equipped with a few different exhaust systems. The 400 std. duty cars received 2″ head pipes with 2 1/4″ tail pipes. Automatic cars used a resonator on the end of the tail pipes but exited out of the resonator with a 2″ angle cut spout. The manual cars had a 2 1/4 tail pipe that exited at the back bumper. Chrome extensions were an option on the Manual cars only. Chrome extensions for these cars had a slight bend in the tip correcting the geometries of the tail pipe allowing the tail pipes once the tip was on to look like they were coming straight out the back of the car. If you opted for the high output version 2 1/4″ head pipes were substituted for the 2″ version. Our systems come 14 ga aluminized with correct head pipes with correct flats where applicable. Correct flanges, correct unequal length mufflers, correct tail pipes, reproduction resonators, gm clamps, reproduction muffler and tail hangers, installation instructions, diagrams and sealant. Chrome tips are available as well as a concourse show package 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, or our performance system with 2 1/2″ head pipes when you have to have larger pipes but don’t want to sacrifice the original look.

1967 - 1969 GM 2 1/4 " Strap Clamp

This strap clamp was used on many of the GM - A Body Muscle Cars.

They come standard with our concours show pkg. or can be optioned with one of our entire systems.

1964 - 1972 GM A - Body Retainer

These retainers were used on the GM A - Body Muscle cars on the muffler hangers. The attaching screw first went through this reatiner and then through the rubber.

They are a Gardner EXhaust exclusive reproduction and come standard with our concours show pkg. or can be optioned for with one of our entire systems.
