    Default Corksport exhaust scavenging demonstration

    A good example of the improvements an exhaust manifold can make. This is the main reason I installed a manifold on my BK, even though I elected not to replace the downpipe at the same time. The OEM manifold scavenges quite poorly. I saw immediate torque gains without any tuning required. (Note if I'd replaced the downpipe tuning would be essential - manifold alone tuning would still be recommended but monitoring mine closely saw good gains with no indications of a tune being necessary - the additional scavenging also raises the knock ceiling, reducing likelyhood of knock occuring)
