ABOUT FLOWTECH

Gary Biggs, a specialist in the exhaust sector, founded Flowtech Performance Exhaust in 1994 with the objective of providing high-quality performance exhaust at an affordable price. Their aim was accomplished, and in less than two decades, Flowtech established itself as the market leader in reasonably priced exhaust systems. Flowtech established a strong market position through the use of aggressive and unique product names such as RaptorTM, TerminatorTM, AfterburnerTM, and WarlockTM. Flowtech has even revived some vintage names, such as Purple HorniesTM.

WHY CHOOOSE FLOWTECH PRODUCTS?

Flowtech developed itself through simple yet effective enhancements such as slotted port flanges that provide additional wiggle space during header installation. They dimpled their tubes at the port to provide additional space for the header bolts and parallel ground their flanges to ensure a tight seal. Flowtech's new Afterburner headers utilize a velocity tube to separate the odd-firing cylinders and improve scavenging. These headers come in a variety of finishes, including polished stainless steel, chrome, ceramic coated, and black painted.

Their innovative Warlock bypass muffler was awarded the SEMA best new product award in 1996 for its groundbreaking open or closed design. When Flowtech was acquired by Holley Performance Products in 1999, the firm maintained a value-oriented philosophy, with an emphasis on late-model vehicles and trucks. For Mustangs, Camaros, and all types of full-size trucks, including diesels, headers and exhaust systems were designed. Today, the same idea is carried forward with the addition of universal X-pipe kits and X-pipe kits with integrated cut-outs. Continuous product upgrades and process improvements will ensure that Flowtech remains the market leader in value-priced exhaust systems.
