CTS Turbo catless downpipe for the Audi A4 B5 1.8T. It replaces the highly restrictive factory catalytic converter, allowing the engine to gain power and produce a fuller sound.
It bolts directly behind the turbo, in place of the stock catalytic converter. It features a nearly 4-inch inlet that tapers to 3 inches, ensuring smooth exhaust gas flow from the turbo, with the rest of the pipe consisting of 3-inch T304 stainless steel that is mandrel-bent and hand-TIG welded. It includes two lambda sensor bungs plus a third for a wideband sensor, and all necessary hardware is included.
Compatible with the 1997–2001 Audi A4 B5 1.8T. A Stage 2 ECU remap is required to prevent 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 to confirm the lead time.
