These Bull-X downpipes can be exchanged 1:1 against the OEM downpipe.
They provide a higher exhaust passage and a lower exhaust back pressure, resulting in increased efficiency, the exhaust gas temperature reduces and relieves the turbocharger.

Available without catalyst, with 100 and 200 cells catalyst.

Ideal for uprated cars.
Pipe diameter: 76mm / 3" (with OEM flanges)


Catalyst information
When selecting a downpipe without a catalytic converter or with a 100/200-cell catalytic converter, there may be an error message of the post-catalytic lambda sensor in the control unit, which does not lead to restrictions in driving operation because the first lambda sensor end is present for the motor control. The post-cat Sensor is only responsible for monitoring the effect of the catalyst. This can be programmed out by adapting the software from a chip tuner.

With most cars up to Euro 3 Emission code, there is no post-cat Sensor and installation is possible without further adjustment and error message.

The wash coat content of HJS ECE and EOBD Kats is significantly higher and is characterized by a very high oxygen storage capacity, which means that errors can be avoided. The EOBD Kats are tested for this topic up to Euro 4. The durability and the use up to the Euro 6 exhaust-gas standard is of course given.
For Euro 5/6 vehicles, the above points can only be avoided if a cat with an ECE selection is made.
