CTS Turbo 200-cell high-flow sports catalytic converter pipe for the Audi A4 B5 1.8T. It replaces the highly restrictive factory catalytic converter, allowing the engine to gain power and sound fuller.
It sits right behind the turbo, in the place of the factory catalytic converter. It features a nearly 4-inch opening that tapers down to 3 inches so that gases pass from the turbo into the pipe without turbulence, and the rest of the pipe is 3-inch T304 stainless steel, mandrel-bent and TIG hand-welded. It includes two lambda probe bungs plus a third one for a wideband sensor, and comes with mounting hardware.
Compatible with the Audi A4 B5 1.8T from 1997 to 2001. A Stage 2 tune is required to prevent the check engine light.
Before installing any exhaust parts on a road-legal vehicle, please consult 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.
