Description

The GrimmSpeed J Pipe/Downpipe is a catted exhaust component crafted from durable aluminum, featuring a 3-inch diameter. This component is specifically designed for the 2015-2021 Subaru WRX models equipped with a manual transmission. It integrates seamlessly with the OEM bracket during installation, allowing for the use of 1/2" thick flanges. The inclusion of a catalytic converter helps manage emissions. From a completely stock vehicle, users can expect a gain of around 45whp (27%) and 70wtq (41%) with the installation of the GrimmSpeed J-Pipe and custom tuning. Note: Installation on 2015-2021 Subaru WRX manual transmissions requires custom tuning. This product is California warning compliant.
