1972 GTO Exhaust System

The 1972 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 that exited behind the rear wheel. The splitter was held into the tail pipe with a lock and key style method. The tail pipe had an expanded section at the end with a formed groove that corresponded to the groove in the splitter. The correct splitter and tail pipe combo has been extinct for a very long time. No longer will the 72 GTO restorer have to settle. Gardner Exhaust is now reproducing the correct reproduction chrome plated splitter and tail pipe combo as original with the correct slotted grooved splitter and correct grooved punched tail pipe. This system will come with correct flanges, clamps, front hangers,attaching hardware, installation instructions diagrams, and sealant Correct reproduction tail hangers 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!

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. The reatainer functioned as a washer to protect the rubber on the hanger. Our retainers have been reproduced from the orginal in the picture and come zinc plated.

This is the correct reproduction splitter for the 1972 GTO. The original splitters used a lock and key method witha v groove and a small punched hole for a carriage bolt. This splitter has been reproduced from the original seen next to it. For the longest time the 72 GTO enthusiast has been forced to put something on their car that is far from what came from the factory no longer does that have to happen. These splitters come chrome plated as original and are available with any of our 1972 GTO systems. They are an identicle reproduction and have been reproduced from the original to the right. We encourage you to compare.

The splitter is just to pretty to not show it as it would look in the car.

Sealant

Originally a clear silicon sealant was used in all the joint to joint connections on most exhaust systems. This was referred to as "grease" in the assembly manual but it was a clear sealant like the one pictured here. After analyzing original samples off our pipes and searching incessantly we came up with a match with the sealant pictured here. This sealant comes as part of any Gardner Exhaust Kit
