I bought A Benz Silent muffler,and put it on my Honda Rubicon....It works great...Reduces muffler noise,and very little,if any power loss! I only use it during turkey season...I have one piece of property that I hunt,and its several miles to it behind A locked gate.I have A key to the gate,but my truck wont make it thru some of the bad mud holes,so it comes in handy for that...The smaller tracks that I hunt,I just walk!...But I was suprised at how much game you can ride up on...One morning,I cut the bike off in the predawn,and A tom started gobblin less than A hundred yds away!
