Performance tuned aftermarket headers can provide much more than just sending exhaust to the back. Apart from having separate tubes for each cylinder to eliminate backpressure due to interference between exhaust pulses, a properly designed header can actually increase engine efficiency, helping to draw more air/fuel mixture into the combustion chamber through a process known as exhaust scavenging.

This high performance exhaust header features a shorty design that is most efficient at providing horsepower gain from idle to mid-range RPM, which brings excitement to street driving and is ideal for street racing.

The piping is constructed from premium 16-gauge(1.59mm) austenitic T304 stainless steel for superior durability. It is fully mandrel bent to maintain high flow rate. TIG welded at all joints, it also combines a cracking and corrosion resistant surface and an obstacle free internal wall. The surface is polished to add an extra layer of protection against wearing in various operating environment.
