Flowmaster – Cat-back System ‘05 - ’10 Ford Mustang GT, 4.6L, FORCE II® SYSTEM, DOR (Dual Out Rear)

Today’s late model Mustang is the king of the muscle cars. Now their prideful owners can install Flowmaster’s new stainless steel Force II® kit (PN817410) and not only achieve great performance and throttle response but superior sound as well – and back it all with a 10-year warranty. The kit includes everything required for installation as well as the signature Flowmaster stainless steel polished tips that exit in the factory cut out locations.  The new kit incorporates all of the benefits of the standard aluminized steel kit with added durability.  The specially tuned 50 Series™ mufflers provide a deep, moderate exterior tone and mild interior sound level. For enthusiasts seeking a more aggressive tone for their pony car, the American Thunder® Classic system is also available. Both are total bolt on installations that do not require welding, and each include zinc-plated sure-seal™ clamps for long life.
