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!
Testimonial: The best company I have ever dealt with
LRS hands down is doing everything right. Every experience I have ever had with them shows just what an amazing company they are. There is a reason I come back time after time, instead of going to those "other" mustang aftermarket websites. Customer service is the name of their game, and they are winning. It does not matter whether you call, email, forum PM, or go to the actual store, they are always incredibly helpful and enthusiastic. (Getting to see the Cobra R in their showroom was awesome). I'm proud to have the LRS windshield banner on my car, because I know they will always have my back.
