I'll second that!! I have the HPS and a buddy had the Bike Man, no comparison there.
Very interesting on these new silencers, as soon as somebody has some actually seat time on the snow, we need some info back.

Believe stock mufflers can not exceed 78 db. If I remember correctly 1 db increase is 10X louder.

Are you coming up to the Edmonton sled show?
So it's only about 180 X louder :face-icon-small-dis. I guess I'm getting old I think I'll pass.

I believe you are wrong on both of those.
From SLP website:
" Most states require sleds to pass one of two tests that were developed by the Society of Automotive Engineers (SAE). These tests are either the SAE J192, an acceleration test through a 150-foot trap with a maximum decibel level of 78 dB at 50 feet, or the SAE J1162, a 15 mile per hour pass by test with a maximum decibel level of 73 dB at 50 feet (see diagram). These tests insure that all stock snowmobiles meet the sound level criteria demanded by each state.
