The CTS B5 A4/Passat 1.8T test pipe is the premier test pipe for your B5 Audi A4 and VW Passat 1.8T. Our test pipe is designed to seamlessly fit in place of your restrictive stock catalytic converter, which is situated immediately after the turbocharger. Our test pipe 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 test pipe. Upon inspection you will notice smooth mandrel bent piping with seamless transitions from the turbocharger to the exhaust system. In addition to being one of the best bang for the buck performance upgrades for A4 owners our test pipe is also very attractive piece. Each 3" test pipe is mandrel bent, hand tig welded. Do you need an additional 02 bung for data logging? Well that's no problem! Tig welding additional 02 bungs can be done for an additional charge.
