Hey guys I just got a 2005 Polaris predator 500. I already have a k&n air filter and a fmf exhaust powercore 4 and it's pretty loud. I assume it's jetted also due to the aftermarket pipe and air filter but other than that it should be all stock. What else can I add to the predator to make it faster and louder? Are there any new mods I can add since the old post asked the same question on here but it was a couple of years ago? Thanks let me know
