1970 -1971 GTO
The 1970 1971 GTO Systems were the same for both automatic and manual transmission cars howver 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 with a splitter placed on the end for aesthetics. Our systems come reproduced from originals, they come with the correct head pipes with correct flats where applicable, correct flanges, mufflers, muffler hangers, gm style clamps installation instructions, diagrams and sealant. Brackets, bolts and splitters our repro tail hangers, and 2 1/2" strap clamps are available. Ask about our concours show pkg when original just is not good enough.

Ask about our turbo mufflers for a little extra roar!

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:

The 1970 - 1971 GTO Hanger is another reproduction that came about due to our belief of a possible hindrance to the fit of one of our exhaust systems.

Our hangers are reproduced from the originals you see here. They use the correct corded rubbers and button head rivets. They are equipped with the correct 5/16 18 weld nut and corresponding screw. They come powder coated chassis black as original with zinc plated brackets and rivets, and are accompanied by installation instructions for easy installment. These hangers may be purchased with one of our exhaust systems. As with all of our reproductions we encourage you to compare with originals.


1967 - 1969 GM 2 1/4 " Strap Clamp

The GM Strap Clamp pictured here is a 2 1/2" strap clamp. It was used exclusively in the GM Muscle Car Market to attach the 1970-1971 GTO Splitter to the tail pipe hanger. The strap clamps that have been available previously for this application were 2 1/4" which can not function properly. We decided to reproduce this clamp after realizing that no matter how nice our 1970 -1971 GTO exhaust systems look they still are incomplete with out the presence of this clamp. Our clamps have been reproduced from the original above and come zinc plated with the correct sheet metal screw.


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.

1970 - 1971 GTO Splitter
This is the correct reproduction splitter for the 1970 - 1971 GTO. Althought these splitters are not our own reproduction they are a very nice copy of the original tips. Original splitters actually were not chrome plated all the way back to the front of the tip when the car came from the factory. These tips are a very nice reproduction of what would have been an NOS tip. We offer these tips with our 1970 - 1971 GTO exhaust systems
1970 - 1971 GTO Tail Hanger Bracket
These are the correct brackets used on all 1970-71 GTO exhaust systems to hold the rear hangers. They come powder coated chassis black and are a Gardner Exhaust exclusive reproduction. The washers seen here are a unique cup washer and until our recent reproduction were not available anywhere leaving the restorer no optons but to come up with originals. Our cup washers are made from our originals and come as part of our rear hanger bracket kit as well as the correct bolts and nuts. This bracket assembly is available with any of our 1970-1971 GT O exhaust sytems and As with all of our reproductions we encourage you to compare them to originals.
