I decided on the Freedom Performance Racing series slip on for my 2010 Road Glide along with the screaming eagle stage one filter kit. The pipe sounds great nice deep throaty sound not too load I can hear the stereo fine .....Not too quiet ended up exactly what I was looking for in an exhaust..... I had Harley do the the stage 1 down load bike runs great I can feel the difference in the torque ......in case any one is interested
