Bull-X Downpipe 3" Ford Focus RS/ST Mk.2 (with ECE*)

You want to get more power out of your turbocharged engine?
Then you should start with a Bull-X product!

The downpipe is a significant part for torque range and power in a turbo system. It´s the connection between the turbocharger and the catback exhaust.
If the diameter of the downpipe is bigger as usual and the passage is higher, the turbocharger is able to lead off the exhaust gas easier and quicker.
This has a positive influence in torque and power.

The advantages at a glance:
• the turbocharger is able to lead off the exhaust gas easier, this is the reason for more power
• better torque range, because the charger can speed up faster
• lower exhaust gas temperature, so the charger and the exhaust manifold will be relieved
• OEM connections for plug and play installation
• *optionally without cat, incl. 200-cell sports cat, with Bull-X 200-cell EOBD sports cat by HJS or with 200-cell HJS sports 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.
