I finally got out this weekend and rode my 08 ds450. I am new to quads but it seems to be lacking power. Hills that I would blast up in 3 gear on my crf 450 had me wondering if I should downshift into 1st on my ds. When I got back from riding I cut that pink wire, and now I will order a slip-on or maybe a full system and a new air filter. Which pipe would give the most bottom end power and any other power upgrades would be great, I mostly ride hills. Don't get me wrong I think the quad is great but just does not have the power that my other toy do.
