CTS Turbo 200-cell high-flow sports catalytic converter downpipe for the Audi A4 B6 1.8T. 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 allow exhaust gases to flow from the turbo to the pipe without turbulence, while the rest of the pipe is 3-inch mandrel-bent T304 stainless steel, TIG hand-welded. It includes two lambda sensor bungs plus a third one for a wideband sensor, and hardware is included.
Compatible with the Audi A4 B6 1.8T. A Stage 2 remap is required to avoid a check engine light.
Before installing any exhaust parts on a registered vehicle, please check the current homologation regulations.
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.
