Product Description

Flowmaster 40 Series
The muffler that started it all, the original 40 Series Muffler is an aggressive sounding street/strip muffler that delivers a powerful “Flowmaster Sound”. If you really want to hear your exhaust system – from both inside and outside of the vehicle, the 40 Series is for you. Available in either black aluminized steel or black 409S Stainless Steel and fully MIG welded for durability.

While the Flowmaster muffler produces more power than the original equipment mufflers, they also produce the unique "Flowmaster sound", which has become the preferred choice of many Mustang enthusiasts. Flowmaster mufflers are constructed with 16 gauge aluminized steel. Flowmaster 3 chamber mufflers (Delta Flow Series) are not as loud as the 2 chamber mufflers.

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!
