Product Description

Dreamscience – RS MK3 3″ Down Pipe De-Cat

The Dreamscience 3″ Down pipe De cat is a 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. We have equipped this system with a threaded boss for the standard oxygen sensor. When designing the RS MK3 Down Pipe De-Cat we made sure we aimed to achieved three important qualities. Enhanced performance, Sharped Sound and a high quality finish. This modification removes the restrictive standard cat and down pipe and replaces it with a 3″ high flowing down pipe. 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 RS.

When carrying out the stage 2 and stage 3 development on the DS Ultima 2+ and DS Ultima 3 maps, The Dreamscience Down pipe De Cat played a key role in achieving high bhp and torque figures. This design allowed the increased air to flow through at a much faster rate increasing power higher in the rev range where it is really needed. With the correct supporting mods of an intake, down pipe de cat, Cat back, the DS Ultima 3 remap achieves 400+ bhp with around 425Ftlbs torque. All Dreamscience maps for the RS MK3 can be sound at the link below;
