Downpipe w Cat (SS) was tested and developed together with the Evolution Line.

The high-flow downpipe is constructed using high-quality stainless steel and, once fitted to the Evolution Line exhaust, it creates a complete system from the manifold to the tailpipes that will further enhance the performance figures: both the torque and power outputs. It incorporates a sporty catalytic converter. This optional downpipe produces an enhanced sound that delivers a pure racing emotion and fantastic feedback at high revs, without unwanted drone, making it suitable for everyday use.
