Tanabe Divorced W/G Catless Downpipe 08+ Impreza WRX/STI
Tanabe Downpipe: The Tanabe Turbine Tube, also known as the Tanabe Downpipe, extracts the most power from turbocharged vehicle applications. Turbo efficiency, power and response is greatly improved. Each downpipe has an EGT Bung with cap for those who wish to monitor exhaust gas temperatures, without having to drill into their downpipe and void their warranty. Replaces pipe from turbo to the stock main catalyzer, which is kept. Best mated when used with any Tanabe catback exhaust system.
