1986-2004 Mustang Flowmaster American Thunder Cat Back Exhaust Dumps
Give your 1986-2004 Mustang a deep, powerful sound with this Flowmaster American Thunder cat back exhaust dump kit! Dumped exhaust is great for use in drag or road race Mustangs that have large rear tires or suspension setups with no room for tailpipes. The included turn-down tips in this kit will dump the exhaust right in front of the rear axle housing taking up less space in the back half of the chassis. This kit features a 2.5-inch mandrel-bent stainless steel tubing flowing into a pair of Super 44 chambered mufflers directly into turn-down exhaust tips. The exhaust turn-down tips can be adjusted, trimmed to length, then clamped in place with the supplied hardware, or welded in permanently. Made to directly bolt to any 1986-2004 Mustang V8 H-pipe or X-pipe with OE-style ball and socket connections. Utilizing the factory hanger locations, including all necessary parts, hardware, and detailed instructions makes for a simple installation. Pick up the classic Flowmaster sound for your 1986-2004 Mustang 5.0/4.6 and start turning heads everywhere you go!

Flowmaster Quality
Since Flowmaster mufflers use sound energy cancellation technology, you don't have to worry about "packing material" deteriorating and getting louder after as little as a few months. The interior case volume of the inside of a Flowmaster muffler is far superior to that of a "straight-pipe" or "straight-through" muffler design. The deflector in a Flowmaster muffler acts as a one-way check valve eliminating reversion back to the engine and creating a low-pressure area to help scavenge the exhaust. Flowmaster's unique style of H-Chamber designs helps control interior resonance inside the cab area of your vehicle. Flowmaster uses fully welded construction for added strength and durability to last even when installed on high-horsepower engines

About This Brand


Flowmaster
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!
