CTS Turbo high-flow catalytic converter for the Audi S4 and S5 B9 with the 3.0 TFSI V6 turbo EA839, from 2018 onwards.
It is CAD-designed to be a direct replacement for the stock catalytic converter and is manufactured from polished T304 stainless steel, with hand-TIG welding and back-purging. Mounting hardware is included (gaskets are not included). With the stock exhaust, the car sounds sportier, with more popping on downshifts, while remaining discreet when cruising and without drone.
On B9 models, O2 sensor spacers or eliminators do not work, so a Stage 2 ECU tune is essential.
Before installing any exhaust parts on a road-registered vehicle, please check 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 timeframe.
