Collection: Flowtech
Flowtech Performance Exhaust was founded in 1994, by exhaust market expert Gary Biggs, with the mission of delivering high-quality performance exhaust at a great value. The mission was successful & in less than 2 decades Flowtech became the leader in value-priced exhaust systems. Flowtech cornered its place in the market with aggressive & memorable product names such as Raptor, Terminator, & Warlock. They even revived some names from back in the day like Purple Hornies. Flowtech made its mark with simple yet effective improvements like slotted port flanges giving added wiggle room during header installation. They dimpled their tubes at the port to make more room for the header bolts & they parallel ground their flanges to assure a tight seal. Flowtech innovations include their unique Afterburner headers which separated the odd firing cylinders with a velocity tube to improve scavenging. Their patented Warlock bypass muffler won the SEMA best new product award for its revolutionary open or closed design in 1996. When Flowtech became part of Holley Performance Products in 1999, the company continued to focus on value, with an emphasis on late model cars & trucks. Headers & exhaust systems were developed for Mustangs, Camaros, & all types of full-size trucks - including diesels. The same innovation continues today with the addition of universal X-pipe kits & X-pipes with built-in cut-outs. Continuous product updates & improvements to manufacturing processes will keep Flowtech a leader in value-priced exhaust systems.
