CTS Turbo B8/B8.5 Audi 1.8T/2.0T High Flow Cat is the premier high flow cat pipe for your Audi A4/A5/Allroad or Q5.

Our B8/B8.5 High Flow Cat is designed to seamlessly fit in place of your restrictive stock catalytic converter, which is situated immediately after the turbocharger. Our B8/B8.5 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 from installing our B8/B8.5 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 B8/B8.5 High Flow Cat. In addition to being one of the best bang for the buck performance upgrades for A4/A5 owners our cat pipe is also a very attractive piece. Each 3 B8/B8.5 High Flow Cat is mandrel bent, hand tig welded. Do you need an additional 02 bung for data logging? Well thats no problem! Extra 02 bung is now included at no extra charge.
