all 4-2-1 systems, dunno if anyone has tried it on a duplex(not slipon) system.
I think themotorhead wrote it/got it/whatever for a Akro or tiforce but I have a Sato 4-2-1 and it freaking screams, and my pluggies are happy perfect light brown. I'd suggest it to everyone w/ a 4-2-1, just check plugs in a week or so. DISREGARD lil black puff when you whack the throttle from idle, TMH says it dont mean nothin and my plug coloring supports that. Try it and let us know---what pipe you got daddy?
