CTS Turbo 200-cell high-flow sports catalytic converter downpipe for the Audi A4, A5, Allroad, and Q5 B8/B8.5 2.0 TFSI. It replaces the highly restrictive factory catalytic converter, allowing the engine to gain power and produce a fuller sound.
It fits directly behind the turbo in place of the stock catalytic converter. It features a nearly 4-inch inlet that tapers to 3 inches to ensure smooth, turbulence-free exhaust gas flow from the turbo, with the remainder of the pipe constructed from 3-inch mandrel-bent T304 stainless steel and hand-TIG welded. It includes two oxygen sensor bungs plus a third for a wideband sensor, and hardware is included.
Compatible with 2009–2016 Audi A4, A5, and A4 Allroad 2.0 TFSI, and 2009–2017 Q5 2.0 TFSI, with either the stock turbo or the CTS K04-X. A Stage 2 ECU tune is required to avoid a check engine light.
Before installing any exhaust components on a road-registered vehicle, please check your local emissions regulations.
