Invidia Catted J-Pipe for 2015–2021 Subaru WRX (Manual Transmission) – High-Flow Catalytic Converter with Wideband O2 Sensor Bung

Description

This is the Invidia Catted J-Pipe and Downpipe. The factory J-pipe/downpipe is highly restrictive by the nature of the design and begins right after the turbocharger leaving much room for improvement. Invidia really opens up the exhaust flow path with their downpipe by developing a unit that combines a larger piping diameter with smooth bends. This will allow the turbocharger to exhale those exhaust gases with fewer restrictions and turbulence for unobstructed flow right out of the cat-back exhaust system. Because of these reasons, downpipes make for the most popular exhaust upgrade that adds a substantial bump in both horsepower and torque with a great reduction in turbo lag.
