1968 Oldsmobile 442 and Hurst Olds Exhaust System

The 1968 Oldsmobile 442 exhaust system consisted of two different exhaust systems. The early cars used 2 1/4″ head pipes and 2 1/4″ chambered tail pipes with perforated internals crimped inside. We have done years of research on these very rare tail pipes and finally came up with originals. It is our belief GM used these tail pipes up until early November of 1968 and then changed production to a 2 1/4″ head pipe with 2″ tail pipes. Both of these exhaust systems used a spot welded on chrome trumpet Our reproduction exhaust system for these cars comes with the correct head pipes, flanges, tail pipes with correct welded on trumpets and wrinkle bends!

(W-31 cars used a similar exhaust system, however the tail pipes juts turned down and were cut at an angle no tip was welded on) The kit also includes correct mufflers, installation instructions, diagrams, sealant, clamps and correct front hangers. Our reproduction tail pipe hangers are available. . Ask about our concourse show package for those of us when original is not good enough.

Ask about our turbo mufflers for a little extra roar!

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 seaman pictured here. This sealant comes as part of any Gardner Exhaust Kit
