In the world of box exhaust, many only think of the SIP Road pipes, but Malossi makes one that has proven itself better on dyno test all over the world. It has similar construction to the SIP Road 3.0 but has better ground clearance because the expansion portion of the exhaust points straight out instead of towards the ground like the SIP. It also features the largest exit tube given the pipe the least restriction of the other box pipes and of course has the build quality you expect from Malossi.
