Description

The CTS Turbo Audi A4 Test Pipe is a performance exhaust component designed for the B6 A4 1.8T models. It replaces the stock catalytic converter located directly after the turbocharger to improve exhaust flow. This test pipe features 3" stainless steel piping, smooth mandrel bends, and includes two O2 sensor bungs, with an option for a third.

The primary benefits of installing this test pipe include substantial power gains, improved exhaust flow, and a more throaty sound. The unit is constructed from T304 stainless steel, is fully TIG welded, and comes with install hardware.
