The Flowmaster Sound is the true tone of American muscle and performance. Available in a wide range of domestic and import applications for automobiles and trucks. Flowmaster mufflers produce more power than OEM and competitive aftermarket products.
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 dynos. Through use of these dynos, 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.

Q: What is a muffler? Are there different types of mufflers?
A: According to our resident expert Deryl Atanasu, Mufflers are positioned by the manufacturer where there is space on the car. All mufflers tend to be placed behind the rear axle, as this allows a lower floor-pan in the passenger compartment. Vehicles with single exaust generally have the muffler placed in a direct line with the tailpipe and just before the exaust tip. Some high-performance vehicles have a dual exaust (i.e. corvettes), where both left and right sides have a muffler in a direct line with the tailpipe and just before the exaust tip. Other vehicles (i.e. camaro, firebird) have a single exaust pipe going back just past the rear axle. It then enters a muffler that is mounted in a side to side position. From there two tailpipes exit the muffler and extend to the rear or out the side of the vehicle behind the rear axle.
