can anybody tell me how loud the yoshi rs3 for a 03 400ex and about how much hp gains you get over stock?

Thanks

I put the yoshi rs3 on my 01 and it is awsome. I cant say how much HP i gained but i could definatly feel a difference in power. It almost sounds stock when it sits and idles, but when you really get on the throttle it really opens up and has a great tone to it.
