X-Force Catted 3 Inch Downpipe 2 x O2 Bungs 2008-2014 WRX / 2008-2021 STI

Description:
X-Forced has released the Pro Series Catted Downpipe to help you improve the performance of your vehicle. One of the more popular first modifications for a turbocharged vehicle is a downpipe simply because they free up a substantial amount of horsepower. Your factory downpipe can be very restrictive because it needs to be compliant with all emissions regulations. X-Force has designed this downpipe with smooth bends which reduces exhaust turbulence under boost, and when combined with 3" piping, you get a significant increase in both horsepower and torque, and you get reduced turbo lag with improved throttle response.
