Polaris Outlaw 525s

Just picked up the near new 2008 outlaw 525s yesterday, and all I can say is that it is FAST... you can just feel how much more lighter it is compared to the IRS. Also installed some pro amrour nerfs, a prm bumper and prm grab bar. Only problem with the machine is when you let off the gas, it makes a very loud chirping noise, I believe it could be the exhaust, could any one verify that? Will post pictures sooon

Aftermarket pipes are known for "throttle dump" noises. The HMF pipes on my Kawie tend to cherry bomb when i let out. If it has the stock pipe check to see if someone removed the baffle, that can also cause strange noises.

It is the stock pipe, I am going to check the baffle now. If worst comes to worst, I will just order another stocker. I heard if you add an aftermarket slip on with out the header, it can actually harm your machine. Is this true?
