Not Road Legal

The Dreamscience 2.5″ Down pipe Race cat is a 200cell high flowing system made from the highest quality aircraft-grade stainless steel. This system has been designed and manufactured by our top technical engineers in the U.K. The high quality cat internals allow for much quicker airflow over standard. We have equipped this system with a threaded boss for the standard oxygen sensor. When designing the Fiesta ST MK8 / Puma ST – Down Pipe Race-cat, we made sure we aimed to achieve several  important qualities:

Optimum performance, Sharped Sound, high quality finish.

This modification removes the restrictive standard cat and down pipe and replaces it with a high flowing Race cat. This will therefore allow the turbo to spool better and faster, increasing acceleration and power. This will also improve throttle response and the torque output of your ST.

This particular replacement will make the biggest difference in performance when changed as it is the most restrictive part in the standard exhaust system. The 2.5″ bore size is designed specifically for stage 2 set ups. A common misconception with down pipes is that bigger is better. From a tuning perspective when designing, a key component to factor in is not only air flow but pressure / back pressure. The design is designed For 99% of customers running basic bolt on’s (Intake, Intercooler, exhausts).  Factoring in that the engine is still only 1.5l / 3cylinder with a small(ish) turbo. Putting the same size diameter down pipe as you would an RS MK2 isn’t always the most effective strategy on the ST MK8 | Puma ST. This will therefore allow the turbo to spool better and faster, increasing acceleration and power. This will also improve throttle response and the torque output of your ST.
