I recently got my used 07 grizzly 700. It came with a HMF tuner and exhaust. It’s way to loud for what I need and how I use it. I did pick up a kolpin after exhaust system to help out but I’d like to see what options are available. The previous owner stated that he removed a baffle from the exaust I am guessing he meant he removed the apart arrest or assembly but I’m not sure. It seems that stock mufflers are not very available so looking to see what options are available and if the HMF optimizer should be removed if I change mufflers.

Thanks
Doc
