What mods you have on your Rhino? I've been courious to hear the sound of a Muzzy. They sound awsome on a Teryx, but that is twin cyclinders.

The muzzy sounds good on the 660 and 700, and it is not crazy loud. It does not sound as good as the muzzy on the teryx. I have seen a 660 with a cdi, sheave, intake, jetting, and the muzzys run 63mph and 0-40 alittle over 5 secs. The jetting and the intake is worth around 2 hp, and the pipe worth around 4.5 hp. Before the pipe and intake it was almost 8 tenths slower 0-40. I would start with around a dj175 with the pipe. Not sure what other mods you have so thats just a guess, a air/fuel ratio gauge is a must for proper tunning. If you have alocal shop have them dyno tune it. I hope this helps.

Just did mine on a 700. I gained about 8.5hp with a Muzzy and MSD. My first run (blue) was with stock exhaust, Rigid Intake, and a Dynatek. The second (red) was MSD, Muzzy, and Rigid Intake.

I'll be taking it out this weekend but I'm happy with the power results. Pulls a lot better than it did.

Still waiting on 2 crush washers that go between the header and motor,on order at temecula motorsports.They have 1 in stock,When there's 2 needed?You think order more???????????


Question: The muzzy came with a heat lube is that just for the header bolts?
is there anything else that gets lube or is the rest dry fit?

Im not your local mechanic...LMAO
