3.0L V6 TDI Secondary Cat / SCR Delete Pipe - VW Touareg / Audi Q7 / Porsche Cayenne (2009-2016)

Built in Canada. Zero compromises.

The SCR/secondary cat section on the 3.0L V6 TDI in the Touareg, Q7, and Cayenne is the last stage of the aftertreatment stack, with urea injection, doser valve, and sensor bungs all living here. This pipe replaces the entire section with a direct-fit 3" stainless delete, the final piece in a full staged build.

Fabricated from 3" 304 stainless steel with full interior backpurge on every TIG weld. Backpurging displaces oxygen from inside the tube during welding, eliminating the oxidation (sugaring) that weakens welds and creates corrosion points over time. Most exhaust fabricators skip this step. We do not.

Modular by design, bolts to factory flanges, compatible with OEM sections upstream or with our Primary Cat Delete Downpipe and DPF Pipe for a full staged build. Upgrade just what you need.

Tune Requirement

Requires a 3.0L V6 TDI ECU tune to clear AdBlue/SCR fault codes and optimize fueling after install.
