This American Thunder® crossmember-back exhaust system is custom designed for the 1964-1966 Ford Mustang and is perfect for the person looking for a complete 2.50-inch dual exhaust system with a moderately aggressive exterior tone, and a moderate interior sound. With easy fit in mind, these 16-gauge aluminized steel systems feature all mandrel-bent tubing, an H-pipe to equalize the exhaust pressures and a pair of specially selected 40 Series Delta Flow performance mufflers for a deep powerful sound. The mandrel-bent 2.50-inch tailpipes tuck up out of the way for maximum clearance and the last few feet is all polished stainless steel for a show car look. Like all Flowmaster® systems, benefits include improved throttle response, power, and mileage. Designed for an easy fit, these systems include all necessary parts, hardware and instructions for an easy installation.
