I got a 91 500 Polaris Indy Sp it is a fast sled i got a set of racing pipes i don't know what kind they are they came with the sled. Im wondering will they give me much power. And what should i jett the sled to so i don't blow it up. And is there any way i do trail driving with racing pipes on??

on that engine i would not trail ride with the pipes, I feel they will be to finicy, I would bet money that you would be rejjetting and clutching from day to day to make it run right. for racing you jet fat and come down, you need to find a brand on the pipes so they can tell you what rpms to run at.
