Description

The Flowmaster 17119 American Thunder Header-Back Exhaust System is designed for most 1964-1972 GM A-Bodies with V8 engines and aftermarket long tube headers. It includes hangers and hardware for easy installation, features mandrel-bent 16-gauge aluminized steel tubing, and Super 40 Series performance mufflers for a moderate to aggressive exterior tone. A built-in balance pipe optimizes performance, and it offers two exit style choices: Slash Cut or Turndown. This is a crossmember-back system and does not fit El Camino models.
