Invidia Downpipe Catted Lower w/ Extra O2 Bungs Manual Subaru 2008-2014 WRX / 2008-2021 STI

The Invidia Lower Catted Downpipe features a divorced wastegate flange and includes 2 O2 sensor bungs for your factory O2 setup, as well as an aftermarket wideband. This is a direct replacement for your factory restrictive downpipe designed to greatly reduce back pressure and turbulence. The result is improved horsepower and torque, along with reduced turbo lag for an improved throttle response.
