These competition-ready JBA Long Tube Headers are dyno-tested to produce horsepower and torque gains throughout the RPM range.

The 1-1/2" Tri-Y Long Tube Headers (6651SJT) consist of large stainless steel primary tubes with a titanium ceramic finish. Overall, the increased performance improves exhaust scavenging.
