GrimmSpeed 2015+ Subaru WRX Equal Length Exhaust Header

Upgraded replacement for the factory exhaust manifold. Features full 304 Stainless Steel construction (flanges, tubing, collector, badge). True equal length runners are CNC bent and trimmed (less than 1% variance), welded inside and outside for longevity and improved flow. Utilizes an innovative cast merge collector for low restriction and smooth flow, designed to fit between the stock skid plate and oil pan without ground clearance loss. Thick 1/2-inch CNC cut flanges and 14-gauge tubing ensure durability. Kit includes all necessary gaskets and hardware, plus a custom slotted J-pipe/turbo bracket to retain factory support. Manufactured and welded in the USA. Aims to provide smooth, restriction-free flow and improved HP and TQ without requiring a tune. This header will dramatically change the iconic Subaru exhaust note by replacing the unequal length header.
