Flowmaster American Thunder Exhaust Systems - Truck/SUV

Product images may differ from actual product appearance.

These systems are designed with the latest technology to provide the best possible performance from a Flowmaster muffler. Flowmaster's systems will both improve acceleration and passing power, as well as increase fuel mileage. Every Flowmaster system is individually engineered and dyno-tested for each application. All tubing is mandrel bent for the best possible exhaust gas flow, and choose from fabricated 409S stainless steel or aluminized steel tubing for corrosion resistance. Made in USA.

Bolt this system on and let people know you've arrived. American Thunder by Flowmaster will deliver the aggressive tone you want and the performance you demand from Flowmaster. Each Flowmaster exhaust system comes with Performance Flowmaster Muffler(s), all pipes with hangers attached, clamps and mounting hardware and detailed installation instructions.

These systems feature mandrel bent 16 gauge tubing, either weld-on or flanged inlet pipe/pipes, specially tuned muffler, clamps, and hangers for that aggressive sound of a dual exhaust system.
