Flowmaster

In 1983 California Sprint Car racers were experiencing 'excessive sound' issues at numerous race tracks and were told to quiet the cars down or lose racing privileges. All attempts to silence the race engines without sacrificing power repeatedly failed. Enter Flowmaster founder Ray Flugger, with over 26+ years of exhaust design experience, and while working out of a small 800 square foot barn in Kenwood, California, created Flowmaster's first patented design of racing silencers. Ray attached handles to ease carrying the square shaped race mufflers through the race pits, and the mufflers became known as the "suitcase muffler." These innovative mufflers were the result of years of development with top race engine builders, thousands of hours of dyno research and "real-world" on-track testing. Today, Flowmaster, Inc. 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 500+ 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.

  "These axlebacks are awesome. The factory exhaust sounds alot better than years past, but these sound great. Installation was a breeze. It took about an hour and you don't even have to raise the vehicle. The only thing I can recommend is to have a set of r"
