These Bull-X downpipes can be exchanged 1:1 against the oem downpipes and they provide a higher exhaust passage, what results in less exhaust back pressure, improved efficiency and lower exhaust gas temperature, which additionally relieves your turbochargers.

These downpipes run from the original turbo flange to 121mm, to 101mm and are rejuvenated to 76mm directly at the original flange.

- OEM Downpipes have 2x catalsysts, our Bull-X Downpipes are available in different versions.
- Incl. Thermalal Isolation
- made of: stainless steel
- Completely TIG welded
- clearly audible soundplus (also with OEM exhaust system)
- if you select the "HJS 200 cells Euro6 cat" no ECU remapping will be necessary / no error message of the catalyst control occurs (only for models without OPF)

Note for models with OPF:
When installing the downpipes, a software adjustment is necessary.
Both the temperature sensors and the differential pressure sensors must be programmed out.

Pre-Facelift: The downpipes are supplied without connections for the sensors to avoid unnecessary costs.
