1968 GTO
The 1968 GTO has the distinction of introducing probably the most unique of any GM Muscle Car exhaust systems. The 68 GTO was available with four different systems. The Std duty manual cars recieved 2" head pipes and 2 1/4" tail pipes, while the HO manual cars were outfitted with 2 1/4" head pipes and 2 1/4" tail pipes. The automatic cars used the same head pipes as the manual cars but a tail pipe that probably would get most employees fired if they pitched it to R&D today. This tail pipe was a 2 1/4 tail pipe that split into two 2" pipes one allowing the gases to exit out the back of the car the other pinched shut just above it. Our 1968 GTO exhaust systems come with the correct head pipes, correct unequal length mufflers, correct tail pipes, yes even the tuner tail pipe for the automatic cars, correct hangers, correct GM style clamps, correct flanges, installation instructions, diagrams and sealant, chrome extension which made use of a GM adapter pipe to correct the geometries of the system are an option, as well as a concours show pkg. to keep the system looking clean and new.

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

1968 GTO Adapter Pipe

These pipes were used on the 1968 GTO to correct the geometries and allow the chrome tips to come straight out the back of the car. Our pipe is seen here next to the original and is available as an option with any 1968 GTO exhaust system.


1968 1972 GTO Muffler Hangers

1968 - 1972 GTO's hangers originally had a small bulge to correspond to the bulge in the clamps that Pontiac used during the day. These clamps and hangers are an exclusive Gardner Exhaust reproduction and will put your GTO over the top in exhaust restoration correctness. The hanger pictured here comes zinc plated, and hand built with corded rubbers and button head rivets to simulate the original and are availble with any of our 1968 - 1972 GTO exhaust systems.

1966 - 1972 GTO Round Bottom Clamp

These clamps are absolutely correct for any 1966 to 1972 GTO restoration. There has never been a high quality reproduction of this clamp or the hanger above that corresponds to it. These clamps are a Gardner Exhaust exclusive reproduction they come zinc plated and are available with any of our Pontiac exhaust systems


1964 - 1969 GM A - Body Tail Pipe Hangers:

These hangers are a reproduction of the orginal hangers used on a good portion of the GM A - Body Muscle Cars. These are our handbuilt hangers with corded rubbers and our reproduction button head rivets and are for those who have to have it just the way the car came from the factory. The hangers pictured here are a Gardner Exhaust Exclusive Reproduction. A similar hanger comes standard with our kits along with the correct screws pictured here.


1967 - 1969 GM 2 1/4 " Strap Clamp

This strap clamp was used on many of the GM - A Body Muscle Cars. It was used to attach the tail pipes to the tail pipe hangers. Our strap clamps have been reproduced from an original and come zinc plated with the correct sheet metal screw. 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. 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. 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.


1968 GTO Chrome Tips

These tips were an option on the 1968 GTO's. On both the manual ransmission and automatic cars they made use of an adapter pipe that first corrected the geometries to have the tail pipe appear as if it was coming out the back of the car and this tip was added to the end of that pipe. The adapter pipe as well as this tip is available on any of our 1968 GTO exhaust systems
