I have an '07 Wolverine with the EPI clutch, modded airbox, aftemarket filter, unplugged the stock exhaust, 2" lift with aftermarket wheels/tires. I'm thinking about getting Hauck Performance to mill the sheave, and thinking about putting a Supertrapp Mudslinger exhaust on it. I live in Northern Nevada, so we don't really have a lot of mud around her, but we have lots of rocks and quite a bit of snow. I was also thinking about adding a winch to the quad as well and ultimately a plow blade. However, I can't do it all so I'm looking for outside opinions to help me decide.

I had a race-equipped WR450 that I just sold, so I love go-fast stuff for the dirt, but I also want something that will increase its utility. So gimme some direction and help me spend my money! Thanks...SC

 

I'd go with the winch, especially if you're going to add a plow later.

 

What is your epi kit? Stall springs, weights and secondary spring? The Hauck machining should work like my UTV Inc sheave where if you use a 1mm shim along with it, it will give you way better low end and rip through mid range good. It will also keep your top end or even increase it slightly depending on your other performance mods. Without installing a 488 bbk you won't a whole lot of the exhaust but definitely better. My friends wolvy 450 has clutch work, hmf, airbox and filter mods and he can hit sixty easy. Just be sure to jet properly and you should like the results of the exhaust and clutch machining.
