1966 GTO Exhaust System

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!

1964 - 1967 GTO Driver Side Flange

This is the correct flange for the 1964 - 1967 GTO Std. Duty Cars. The flange pictured here was used on everything except the 1967 HO GTO's. on the driver side head pipes. Our flanges are made by the original manufacturer but don't bother going to look for them because we own them all and the tooling was destroyed. These flanges come with the correct holes for the clutch return spring on the 1964 - 1965 GTO's These flanges come standard with any of our 1965 -1967 GTO kits

1964 - 1967 GTO Passenger Side Flange

This is the correct Passenger side flange for the 1964 - 1967 GTO's for all except the HO 1967's. These flanges come standard with any of our early GTO exhaust systems.

1966 - 1967 GTO Muffler Hangers

These hangers are correct for 1966 - 1967 GTO's the 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 1966 - 1967 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.

1966 GTO and 1967 GTO Automatic Tips

These tips were an option on any 1966 GTO and 1967 GTO Automatic Exhaust Systems. They come stainless steel. We believe the original may have been chrome plated with stainless underneath.They are not our reproduction but we have compared them with our original tips and are pleased to offer them with our 1966 and 1967 GTO exhaust 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.

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
