Product Description

For the Mustang owner looking for a complete exhaust system with an aggressive tone for their high horsepower Fox Mustang. With easy fit in mind, these Delta Force systems from Flowmaster are mandrel bent for maximum performance and include specially selected mufflers. Delta Force systems deliver an aggressive exterior tone and are suited to the Mustang enthusiast who wants their performance to be heard. Like all Flowmaster systems, the Delta Force benefits include improved throttle response, power and mileage. Designed for an easy fit, these Mustang exhaust systems include all necessary parts and hardware for easy installation.

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. Imagine filling a "straight-pipe" or "straight-through" muffler with water vs. filling a Flowmaster muffler with water. Which one do think would hold substantially more volume? The deflector in a Flowmaster muffler acts as a one way check valve eliminating reversion back to the engine and creates a low pressure area to help scavenge the exhaust. Flowmasters unique style of H-Chamber designs help control interior resonance inside the cab area of your Mustang. "Straight-through" muffler designs cannot. Flowmasters use fully welded construction for added strength and durability to last even when installed on high horsepower engines.

About This Brand

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!
