I originally was planning on purchasing ths MBRP race silencer but I ended up getting the trail version which is a little quieter, generally to prevent myself from getting tickets. Now I do agree It's rude to over do it with the noise, but you also need to consider that these people living near the trails do know where they live. If they are totally against the sound of sleds flying through I strongly recomend moving. And if so let me know because maybe i'll buy the place and love it. Sorry, I'm not trying to be rude, just making a point.
