1965 Oldsmobile 442 Exhaust System

The 1965 Oldsmobile 442 exhaust system consisted of 2 1/4″ head pipes and 2″ tail pipes with a 2 1/2″ chambered section welded on. The outlet of the tail pipe used a stainless steel rolled tip on the end of the tail pipe to accentuate the outlet. Our reproduction exhaust system for these cars comes with the correct head pipes, flanges, tail pipes with correct chambered section, correct perforated internals and stainless steel rolled tips welded to outlet. The kit also includes correct mufflers, installation instructions, diagrams, sealant, clamps and correct front and rear hangers. 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!

This is the correct style clamp for the 1965 - 1972 442's. These clamps come standard with one of our 442 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
