I did not want a loud muffler or a restrictive one either. I was looking for some performance gain on my tow rig but didn't want it to be loud. You can look straight through the muffler so I was skeptical as to how it would sound but at least I knew there would not be any restriction issues. I was very pleased at the sound: a low subdued growl, deeper tone than stock but still quiet. I don't want to upset neighbors or fellow campers when I warm my rig up in the morning and I don't have to worry about that with this muffler. My exhaust setup is 2 into 1 ( 1 3/4" downpipes into a 2 1/2" pipe)and the original muffler had a 2 1/2" inlet and only a 2" outletw/ 2" tailpipe. The new muffler w/ 2 1/2" tailpipe gave it some extra go power so I'm a "Happy Camper" !
