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.
The complete ''Cat-Back'' 2-1/2'' systems use Delta Flow two-chamber mufflers and fully aluminized 2-1/2'' pipes, while the 3'' systems use Delta Force technology mufflers and fully aluminized 3'' pipes.

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.
Constructed to fit O.E.M. hangers and mounting positions (bolting directly to catalytic converter.) 3-chamber mufflers are built with welded heat shields and all pipes are 2-1/2'' aluminized tubing.
