Flowmaster 817457 "American Thunder" Stainless Header Back Exhaust Kit
Fits 1978-1988, General Motors A body cars

The "American Thunder" exhaust kit from Flowmaster features "Super 40" mufflers that deliver an aggressive tone that you can hear both from inside and outside of the vehicle. It's that unique "Flowmaster sound" that is the true tone of American muscle and performance. The kit is made from 16 gauge 409S stainless steel tubing that has been mandrel bent for minimum flow restriction. This is a totally bolt-on kit that requires no welding for a clean, simple installation. The kit uses all factory hangers and mounts and includes zinc plated clamps that resist corrosion.
