CTS Turbo B7 Audi A4 2.0T Test Pipe

The CTS Turbo B7 A4 2.0T test pipe is the premier test pipe for your B7 Audi A4 2.0T. It drops straight in where the restrictive stock catalytic converter sits, right after the turbocharger, freeing up exhaust flow for substantial power gains and a throatier sound. It's one of the best bang-for-the-buck upgrades for A4 owners — and a genuinely attractive piece. Our cat-back exhaust bolts directly to it, so future upgrades are painless.

Built from 3" stainless steel with smooth mandrel bends and two O2 sensor bungs (with an option for a third). Need extra data-logging capability? A third O2 bung for a wide-band sensor is now included at no extra charge.

A high-flow cat or test pipe will trigger a CEL without proper tuning — Stage 2 software is strongly recommended. CTS Turbo recommends choosing a high-flow cat for the sake of the environment.
