I have a few mods already. Ihave a dyno port single pipe would a can help me out? If so any place I can get one cheap.

probably not....but it would sound good....I would get a dyno port or mbrp can for your sled if you wanted a good one.

clutching and gears is definetly the most bang for your buck..

Go to the web site for Dyno port. They did R&D on a 800 and tell how each phase upped the HP on a dyno. They show how a can adds almost no HP after its already been piped.
