Description

The CTS Turbo B5 Audi A4 1.8T test pipe is engineered as a direct fit replacement for your restrictive stock catalytic converter, located immediately after the turbocharger. The construction utilizes 3-inch T304 stainless steel piping, featuring smooth mandrel bends and a fully TIG-welded design for optimal durability and performance. Key product details include T304 stainless steel construction and mandrel-bent piping. The test pipe comes equipped with two O2 sensor bungs, with the option for a third at no additional cost, which is beneficial for data logging. Install hardware is included for convenience. This test pipe is intended for competition use and is not legal for highway or street vehicles. To prevent a Check Engine Light (CEL) from illuminating, proper tuning software is required. CTS Turbo recommends using stage 2 software and a high-flow catalytic converter for environmental considerations.
