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.

Dual Rear Exit Exhaust Systems (DOR)
The DOR systems are designed for the person who wants that custom look of a dual exhaust on a late model vehicle that came with a factory single exhaust. 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.

Dual Side Exit Exhaust Systems (DOS)
The DOS systems are designed for the person who wants that custom look of a dual exhaust on a late model vehicle that came with a factory single exhaust. These systems feature mandrel bent 16 gauge tubing, either weld-on or flanged inlet pipe/pipes, specially tuned muffler, clamps, hangers and stainless steel exhaust tips for that aggressive look and sound of a dual exhaust system. Recommended for towing applications.

Single Side Exit Exhaust Systems (SOS)
The SOS system is for the person who wants a subdued, but custom look, with all the benefits of a Flowmaster exhaust system. These systems feature mandrel bent 16 gauge tubing, either weld-on or flanged inlet pipe/pipes, specially tuned muffler, clamps, hangers and stainless steel exhaust tip exiting in the factory location out the side behind the rear tire of the vehicle.

Single Rear Exit Exhaust Systems (SOR)
