I have an 06 500EFI.
What is ballpark stock HP??
What would be the gains with a slip-on??
What would be the gains with a powercomander and good map?
Thanx

 

Some one from WI, cool. I am sorry to say there is not an exhaust made that is worth the money, for what you gainon a Polaris. You may see some gains with and exhaust and a programmer, but not enough to make it worth the cost. I have an 800EFI and a 500efi. The biggest gain you will see on the 500 is from a clutch kit. I think I read the 500 EFI is about 38-40HP. Vern

 

Big Gun makes a slip-on and Powercomander looks as though they have a unit in the works.
Was gonna do the clutch after I got some more time on it this summer.
Big Guns site said 3.5 gain I know that's a stretch but hoped 5+ with both mods.
Guess I'll just wait and see what else comes around.
Guess I'll just sit on what I have for now.

 

Email me and I can let you know what I found
