Flowmaster American Thunder Catback
Flowmaster's new American Thunder Catback system for the 2005-2010 Mustang GT & GT500 takes performance to the next level! Developed and proven on the dyno, this dual 3.00" Mustang Catback Exhaust System maximizes the breathing of Ford's much-respected modular 4.6L 3V & 5.4L 4V V8 engines, delivering increased engine power, torque and throttle response. Fully mandrel bent, it features a Scavenger Series® X-pipe assembly for mid range torque improvement and a pair of mustang-specific 60 Series™ mufflers with Delta Flow® technology. The result is an incredibly deep, powerful exterior sound with a moderate interior sound level. The X-pipe is the cut & clamp design allowing the retention of the stock catalytic converters. These American Thunder systems deliver a moderate to aggressive interior and exterior tone and are suited to the Mustang enthusiast who wants their performance to be heard!
Flowmaster mufflers are proudly made in the U.S.A. and the quality shows in this American Thunder Catback. Constructed with 2.5", mandrel bent tubing, this Catback flows much better than your factory exhaust. Flowmaster utilizes 409s Stainless steel to ensure long lasting performance! Designed for an easy fit, these Mustang exhaust systems include all necessary parts and hardware for easy installation.
Flowmaster - The Exhaust Technology Company Flowmaster operates the only exhaust Research & Design facilities of its kind in the world, centered around the SuperFlow SF-7100 engine dynamometer complete with E.C.A. (engine cycle analysis) equipment and also SuperFlow chassis dyno's.
Through use of these dyno's, Flowmaster's engineering staff can track the complete engine cycle in millionths of a second and can obtain exact technical data of each degree of cam rotation, from induction to the tip of the exhaust system, while also showing the power numbers that really matter, the power numbers "to the ground."
Flowmaster also utilizes Spectrum Analyzers to fine "tune" the sound of each of the eleven different series of mufflers that Flowmaster currently offers, both for peak performance and just the right sound levels and tones. Flowmaster's dedication to quality is what makes them the exhaust industry leader for Latemodel Mustangs and SVT Lightnings!
