CTS Turbo B7 Audi A4 2.0T High Flow Cat Pipe

The CTS Turbo high-flow cat pipe is the go-to upgrade for the 2006-2008 Audi B7 A4 2.0T. It drops straight in where the restrictive factory catalytic converter sits — right off the turbocharger — and trades that choke point for smooth, free-flowing 3" stainless. The result is real power gains, better exhaust flow, and a throatier note. A near-4" flare tapers into the 3" piping so exhaust gas transitions cleanly out of the turbo, and it is a genuinely good-looking piece under the car.
