The CTS B8 A4/A5 2.0T cattest pipe is the premier cat pipe for your Audi A4 or A5 2.0T.  Our cat pipe is designed to fit seamlessly in place of your restrictive stock catalytic converter, which is situated immediately after the turbocharger.  Our catted test pipe features 3" stainless steel piping, smooth mandrel bends, and 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 cat pipe.  Upon inspection, you will notice a flare nearly 4", then tapers to 3", designed to allow for optimal flow as the exhaust gas transitions from the turbocharger to the cat pipe.  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" test pipe is mandrel bent hand tig welded.
