These headers come with 3/8 IN thick laser-cut head flanges and gaskets that are designed to match the head port for a leak-free seal.

Y-Pipe
Dual High Flow Catalytic Converters:
This system utilizes 400 CPSI (cell per square inch) catalytic converters are used for maximum flow.

Construction:
Constructed of mandrel-bent dual 3 IN stainless steel piping which transitions into single 3-1/2 IN piping to reduce back pressure and improve flow

True Merge Collectors:
Eliminates dead space that can cause turbulence and hinder flow.
