Chevrolet Silverado Flowmaster Products 

All Flowmaster muffler tips are stainless steel and embossed the the Flowmaster logo.

Flowmaster was founded in 1983, and today is housed in two ultra-modern facilities together totaling over 400,000 sq. ft., one in Santa Rosa, and the other in West Sacramento, California. Flowmaster employs over 250+ workers dedicated to building the highest quality U.S. made exhaust products available.

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, Flowmasters 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.
