I purchased and installed a set of V & H "Monster" Ovals on my 2007 Ultra last week, took a ride with my honey on the back, for a trip to one of our favorite 'eaterys'.
maybe 6-8 miles there and back and took them off the next day and back to the stock mufflers.
The ad said 'stereo friendly' and disproves the theory that more horsepower means louder. I want you to know that we couldn't hear anything but the mufflers at 65 and lower.
OK, I believed what I read plus the fact that usually the greater internal volume of the 'cans' should have helped 'pass the gas' without the noise (depending on internal baffles).
I went back to my automobile logic of years ago when I had my favorite muffler shop put dual pipes and mufflers on my Chevy V8.
I told him to put something on that made more power but not noise so he put on 2 Corvette resonators. They were bigger (volume wise) and quiet. Yes, the power increase was very obvious.
Then you take companies like FLOWMASTER, who have been building auto mufflers for years that are quiet and 'flow the gas'.
I guess I will have to hang at the Harley dealer and see if I can find someone with those SE Touring mufflers that some of you have referred to.
BTW, the drop in performance going back to the 'stock' HD mufflers from the V & H ovals, was significant but we can hear the stereo and the HD growl of the exhaust.
