I have an 14outlander 800 stock exhaust I’m looking for an aftermarket hmf swamp series exhaust with the fuel tuner to give me a little more power. I do not want a loud exhaust I do alot of night riding and don’t need to upset people. So can anyone tell me how much of a difference in sound it is when riding 20+mph and at a high rpm and do you run the full system or just the slip on?
