HPS silencer
The sound levels mentioned above were indicated to me as well. HPS openly admitted to the M7 silencer "bog". Scott said that silencer worked well on the dyno, but, out on the snow showed the issue. That is why all silencers are now run on the snow as well as the dyno before being sold. I've had a couple of HPS silencers now, and will pretty much stick with them because the performance, testing, and quality of the HPS silencer are second to none imo.
