  • Regular price $299.99 USD

The CTS B7 A4 2.0T High Flow Cat Pipe is the premier cat pipe for your 2006-2008 Audi A4 2.0T.

Our high-flow cat is designed to seamlessly fit in place of your restrictive stock catalytic converter, which is situated immediately after the turbocharger.  Our high-flow cat features 3" stainless steel piping, smooth mandrel bends, two 02 sensor bungs with an option for a third.  Substantial power gains, improved exhaust flow and a more throaty sound are the main benefits of installing our high-flow cat.  Upon inspection you will notice a flare which is nearly 4", this flare then tapers to 3" and is designed to allow for optimal flow as the exhaust gas transitions from the turbocharger to the high-flow cat.  In addition to being one of the best bang for the buck performance upgrades for A4 owners, our cat pipe is also a very attractive piece.  Each 3" high-flow cat is mandrel-bent, hand tig welded.  Do you need an additional 02 bung for data logging?  Well, that's no problem!  Tig welding additional 02 bungs can be done for an additional charge.
