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 of 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, that's no problem! Extra 02 bung is now included at no extra charge.
