Bull-X Downpipe 3″ Ford Focus ST Mk.3 250 hp (with ECE*)

The 3″/ 76mm downpipe for the Ford Focus MK3 ST of HG-Motorsport can be replaced 1 to 1 through the serial part. Perfect fit and high quality material make this product a top product from our range. The flange is designed without impact edges for flow optimization. By optimizing the diameter, piping and/or catalyst of the turbocharger can be greatly relieved. A lower back pressure and thermal relief generate a significant increase in torque, power, previous response and the same time an extension of the lifetime.

Technical details

Plug´n´Play- solution – perfectly fitting and can be exchanged simply fot the original part
76mm/3″ diameter
Flange without impact edges
High Quality material
stainless steel tig welded
Made in Germany – true quality from our own manufacture
flow-optimized and performance enhanced. Improvment of durability and response
optimal remove of exhaust gases – without disturbing edges at the transitions
Designed and developed with flow simulation. Also Bench tested!
No more heatbuilding into the charger and so less thermals load at the turbo.
Besster response and more performance
better ecaust sound (especially when you´re combining this downpipe with a sport exhaust system)
*optionally without cat, incl. 100-cell sports 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

30% More exhaustgases permission to pass

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 euro 6 norm is selected. (No approval)
