The CTS Turbo B8/B8.5 Audi 1.8T/2.0T high-flow catalytic converter is the first high-flow catalytic converter for your Audi A4/A5/Allroad or Q5.
The B8/B8.5 high-flow catalytic converter is designed to fit precisely in place of your restrictive original catalytic converter, located immediately after the turbocharger. It is made of 3-inch (76mm) stainless steel, bent, and equipped with two O2 sensor bungs with an option for a third. Substantial power gains, improved exhaust flow and a more "sporty" sound are the main benefits of installing this B8/B8.5 high-flow catalytic converter. During inspection, you will notice a flare of nearly 4 inches, which then narrows to 3 inches and is designed to allow optimal flow as the exhaust gases travel from the turbocharger to the B8/B8.5 high-flow catalytic converter. In addition to being one of the best performance upgrades for A4/A5 owners, this catalytic converter also features a very nice finish.
Each 3-inch B8/B8.5 high-flow catalytic converter is mandrel-bent and hand TIG welded. Need an extra O2 plug for data logging? No problem! An extra O2 plug is now included at no additional cost.
