Overview:
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. The system is covered by our 3-year Limited Warranty. Connects to existing header collector reducer cones or manifold downpipes(not included.) If you prefer a full stainless steel system with a Lifetime Limited Warranty, check out exhaust system #817273. Notes: For non GT and hardtop models.
