The left side downpipe on the S58 connects to a "crossover" pipe that runs beneath the transmission and links up with the mid pipes on the left side. Unfortunately, the stock shape of the crossover pipe is oval to create enough clearance underneath the transmission. This alteration from a round tube to an oval causes turbulence within the pipe, leading to a restriction in exhaust flow. CTS Turbo has designed a crossover pipe to eliminate this turbulence that is created by the factory system and ditched the oval design for a round circular design for increased flow and horsepower!
