1970 Nova Exhaust System

The 1970 Nova dual exhaust system consisted of 2 1/4″ head pipes on both the big block and the small block cars. The small block cars had the pipes necked down to 2″ at the manifold while the big blocks were expanded up to 2 1/2″. Both systems used 2 1/4″ over the axle pipes and 2″ tail pipes ending mid way back behind the rear wheel and the bumper, resonators were used on the small block cars.

This is the correct stud kit for the 1957-1972 Chevys. This stud kit has the correct dog point on the studs and uses the correct stove nuts as original. This kit is available with any of our Chevy 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
