New Jackpot XXX Hi Output head pipe for high HP 2009-2013 Harley FLH applications. This pipe features tapered primaries (an industry first!), large collector which flows almost twice as much as our standard 2/1/2, along with several other new features. Full stainless steel construction and retains factory heat shields. We will be officially releasing this pipe at V Twin Expo in Cincinnati on Feb 2nd. More info to come....
Forgive my ignorance - what are "tapered primaries"?
The XXX pipe features tapered primaries rather than stepped. While it is very complex to build, tapering is superior to stepping from a flow dynamic standpoint. Tapering allows for extremely smooth transitions as there is no "step" to disrupt the pressure/energy waves in the system. This is the norm on high end Japanese and Euro systems
What kind of power difference are you getting with that head pipe compared to your current 2-1-2?
The Jackpot XXX pipe is designed specifically for high HP builds, on a 120HP combination this pipe will generally make 3-5HP/Tq over our standard 2/1/2 head pipe.
What are the tapered primaries on our Jackpot XXX head pipe? Rather than stepping the pipe we taper the primary for a gradual transition. While the physics and theory is the same as a stepped pipe, a taper is superior from a flow standpoint as there are no "steps" to disturb the pressure wave. This also makes for a cleaner, more streamlined system with less joints and welds. In R&D we focus on maximum performance with best overall design/construction.
So for stock HP bikes or minimal tuning, the current 2/1/2 should be (more than) sufficient? Or would a stock bike gain anything from the XXX? I'm only wanting to change the header once and I'm ready to pull the trigger and get it done before it gets hot down here.
