Overview

The PLM header manifold is an equal-length performance component for 2015-2021 Subaru WRX vehicles.
Show original supplier description
The PLM power-driven equal-length header manifold is designed to optimize exhaust flow and thermal management in 2015-2021 Subaru WRX models. By converting the turbo system to an external wastegate setup, the manifold provides superior boost control, effectively mitigating boost creep and spikes even on stock turbo setups. Constructed from 18-gauge 304 stainless steel with 1.5-inch piping and 0.38-inch CNC-machined flanges, this one-piece unit features hand-TIG welded joints for enhanced durability. Compatibility is specific to 2015-2021 Subaru WRX (VA) models. Please note that this product will NOT fit other aftermarket exhaust systems and is not compatible with the SPT model. Additionally, external wastegates are sold separately, and while the manifold includes hardware for the skid plate, it does not include extra bolts, gaskets, or clamps, which may be reused from the factory setup.
