Bull-X Downpipe Ford Focus ST MK.3 250HP | HJS 200-cell ECE sport catalytic converter (HGDPFO05-4)

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.
