Description

Optimal downpipe kit for Subaru WRX STI 2007-2018. Made from high-quality cast stainless steel 1.4301 (SS304) for durability and corrosion resistance. Features a Ø76mm (3") diameter for optimized performance and flow. CAD-designed and flow-optimised. Includes a lambda probe connection and a high-quality racing metal catalytic converter (300 CPSI with EU6 coating). 100% perfect fit, easy to replace with the standard part. Minimizes thermal load on the turbocharger, increasing service life and optimizing performance.
