Description

The GrimmSpeed Catted J-Pipe/Downpipe is meticulously engineered for the 2015-2021 Subaru WRX, specifically models equipped with a 6-speed manual transmission. This component is designed as a direct bolt-on replacement, ensuring ease of installation and a hassle-free upgrade. Its 3-inch diameter and robust cast aluminum construction are optimized to fit perfectly within the tight underbody packaging of the WRX, maintaining excellent ground clearance without sacrificing performance potential. When installed on a completely stock vehicle and paired with custom tuning, users can expect significant increases in power and torque. Reported gains from such a setup are approximately 45 wheel horsepower and 70 wheel-torque. Custom tuning is a recommended requirement for optimal performance and to ensure proper engine function with this modification.
