CTS Turbo B8/B8.5 Audi A4/A5/AllRoad/Q5 1.8T/2.0T High Flow Catalytic Converter

Description

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.
