Description

Flowtech LS turbo headers improve smooth-flow engine breathing and increase cylinder scavenging effect by providing consistent tubing diameters. Constructed of heavy-duty, 16-gauge stainless steel, they're available in natural, black painted, and ceramic coated finishes. These headers offer 1 3/4 and 1 7/8 in. tubing diameters for increased exhaust flow, increased performance, and improved throttle response. A 3 in. collector provides additional strength and durability.
