Full Yosh 4-2-1 exhaust on Gen II

[Hobo]

I was running an R-77 full system on my 09', FARRRKK best thing I ever did. The thing use to launch up on the back wheel at 90mph in 3rd. Totally stock besides the system, No pc, No BMC. Got it dynoed the A/F was spot on 13.5 across the range. It was wet that day it topped out at 190rwhp, embarassing as it is ... its the first time I ever used the mode selector (c) all the way home, dont tell anybody, it frightened the hell outta me, till I got used to it !

Which Brocks are you now running and how does it compare to the yosh in terms of weight and performance?

ive got the titanium megaphone 4-1 system, pretty light, way louder, and i loooove how loud it is!!! the yosh sounded great but a little too quiet even with the baffle out
