I know there has been many discussions regarding aftermarket exhaust systems for the XR650, but I would like some up to date feedback from those that have used the following systems: FMF Powerbomb header with the FMF Q muffler-I know the muffler is quiet enough to meet the 96db limit, but how is the power compared to stock and has the system lasted without falling apart. Pro Circuit Type 496-I had this muffler on a YZ426 and it was very well made. I would like to know if it meets the 96db limit on an XR650 and how it affects the power. Any other feedback is welcome, I am only interested in a system that is at least 96db quiet. Right now I am using the stock system with the HRC tip.
