DOWNPIPE / DE CAT. [MK4 FOCUS ST]

DOWNPIPE / DE CAT. [MK4 FOCUS ST]

The Dreamscience 3″ Downpipe / De Cat is made from mandrel bent 304 grade aircraft spec stainless steel. All systems have been designed and manufactured by engineers in the U.K. We have equipped each system with a threaded boss for the standard oxygen sensor.

When developing this component, we made sure we achieved several key factors. Optimum Performance; Sharped Sound; A High Quality Finish. We found this particular replacement makes one of the biggest differences in performance when changed, as this the most restrictive part in the standard exhaust system. Therefore, this upgrade allows the turbo to spool greater and faster, thus increasing acceleration and power. This will also improve your ST’s throttle response and the overall torque output.

The 3″ Downpipe / De Cat shows significant improvement is flow and performance over its sports cat equivalent. It is important to note that this De-Cat system is Not Road Legal and will not pass a U.K. MOT emissions test.
