Honda Civic Flowtech Products 

Flowtech has been an innovator in exhaust design since it debuted its unique headers and mufflers in 1994. With slotted flange holes, dimpled tubes at the exhaust ports, and separate velocity tubes for better scavenging, Flowtech's After Burner header certainly was one product of theirs that made some waves with its easy installation and effective design. When Holley acquired Flowtech in 1999, the innovation continued with X-pipe kits and new exhaust applications, all of which are designed by Flowtech to produce the most bang for the buck. And really, if Holley is behind the brand, we know there has to be something to it.
