1974 Firebird Trans Am Super Duty Exhaust System

In 1974 if you stepped up your Firebird order to the super rare Super Duty your head pipes and over axle pipes would have been extra-large to others of the day at 2 1/2″ and larger tail pipes than the base Firebird at 2 1/4″. Our Super Duty Firebird Exhaust systems have been reproduced from originals and come with the correct head pipes with correct flats, correct over axle pipes, correct tail pipes with exact original bracket welded on, correct transverse muffler, GM style clamps, installation instructions, diagrams and sealant. Reproduction cast flanges, muffler hangers and tail hangers are available with our systems as well as our reproduction chrome tips. Ask about our concourse show package for those of us who like the restoration to be a little more real than real.

1970-1974 Firebird Muffler Hanger:

These hangers are
one of only a few pieces we offer that are not one of our reproduction pieces. We have always said that it is not necesarry to reproduce a piece if it is being made properly. Both this muffler hanger and the tail pipe hangers are excellent reproduction pieces, we know this because we helped in the reproduction process by lending out our originals. This hanger comes zinc plated to aid in longevity

1966 - 1974 Pontiac Clamp

These clamps are absolutely correct for any 1967 to 1974 Firebird restoration. There has never been a high quality reproduction of this clamp. Our clamps have been reproduced from the clamp picturted here come zinc plated and are available with any of our 1967 - 1974 firebird exhaust systems.

1970-1974 Firebird Tail Pipe Hangers:

These hangesr are a very nice reproduction of the original and come with the correct screws to help hang the tail pipe properly. They come zinc plated to aid in longevity.

1974 Firebird Chrome Exhaust Extensions:

1971 - 1973 Reproduction Firebird chrome tips are an excellent reproduction of the original seen here. Our tips are distinguised only from original by the part number that can't be seen on the inlet of the tip once it is inserted into the tail pipe, and our superior chrome plating. These tips are available with any of our 1971 - 1973 Firebird or Trans Am exhaust 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
