Ok well as you can see by my name, i have a 05 yamaha wolverine 350. I am wanting to get more power out of my quad. And the first thing that popped into my mind is a pipe. I have read that it makes 7-10hp more than stock. Is this true? The pipe im talking about is the slip on hmf pipe. Please tell me if im correct or correct me if im wrong, but isn`t that pipe the only one available for my my 05 wolverine. I also like the grunt they have aswell becase ive watched videos on youtube of them. But from vidoes ive watched they aren`t too loud. I like a little grunt, but not over the top. And for all of you that have them, how many more mph do you get on the top end? Sorry for all the question but i am curious and i am trying to see if its a good buy or not.

Thanks in advanced
