CTS Turbo catless downpipe for 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 sits directly behind the turbo, in place of the factory catalytic converter. It features a nearly 4-inch inlet that tapers down to 3 inches to ensure smooth exhaust flow from the turbo, with the remainder being a 3-inch mandrel-bent T304 stainless steel pipe that is hand TIG-welded. It includes two lambda sensor bungs plus a third one 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 factory turbo or the CTS K04-X. A Stage 2 ECU tune is required to avoid a check engine light.
Competition use only. This part removes the catalytic converter and is not street legal.
Delivery time 2 to 30 days. This part may not be in stock in Spain and is ordered from the manufacturer based on availability. If you need it by a specific date, please contact us before purchasing so we can confirm the lead time.
