Flowmaster True Dual Exhaust Systems

Product images may differ from actual product appearance.

True Dual exhaust systems are built with maximum performance and aggressive looks in mind. These systems feature mandrel bent 16-guage aluminized steel tubing, specially tuned mufflers, weld-on or flanged cross-over pipes, clamps, hangers, mounting hardware and stainless steel tips that complete that custom installation for that aggressive performance look and sound.

American Thunder
As the name implies, bolt this system on and you'll let people know you've arrived. If you are looking for the famous, full-on ''Flowmaster sound'', look no further. American Thunder will deliver the aggressive tone you want, as well as the performance you demand from Flowmaster.

Force - II
Wanna let folks know you've got a Flowmaster system under your vehicle when you ''open it up,'' but don't want a lot of interior resonance? Then check out the Force-II system. Designed to provide plenty of ''Flowmaster sound'' under acceleration but lower sound levels while cruising, it may just be the perfect system for you.
