Fits all model year S13 S14 S15 SR20DET.

The Turbine Tube, also known as a 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.

Note: Each of the Tanabe Sustec downpipe comes with an EGT bung that is already pre-welded for ease of tuning or adding EGT and/or air fuel ratio gauge.
