Bull-X Downpipe for VW Polo 6R WRC (with ECE*)

BULL-X Exhausts produces downpipes at the highest level.

Like the stainless steel Downpipe for the VW Polo 6R WRC.

It is perfect in series, as well as for tuned engines. It also increases the engine power, increases the gas response and degreases the exhaust temperature.

Technical details:

- Pipe diameter: 89mm inlet, 76mm in beyond
- performance-enhancing
- Optionally available without catalyst, with 100 and 200 cell sports catalyst or with HJS sports catalyst and EEC type-approval
- tig welded
- material: stainless steel
- complete with adapter for mounting on the original exhaust system
- *available with or without approval, depending on the version

If you selected a downpipe without cat, 100/200 cell Sportcatalyst as well as HJS EOBD Kat, the article has no approval. Only legal on the streets when you selected the ECE-Cat / Incl. ECE type approval.

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.
