This optional upgrade turns the Evolution Line into a complete system. It is constructed from high-quality durable stainless steel. High-flow downpipes increase power and produce an improved Akrapovič sound as the revs rise. Fitted with high-flow catalytic converters (300 cpsi). The ECU will need to be remapped when this downpipe set is fitted.
