Okay .. I'll admit it, I must be getting old. The Vance and Hines circa 2002 4" mufflers were getting to me a bit on the highway. Also, there are not EPA complaint (no stamp) and we've had guys stopped at the Utah border and ticketed for non stamped slip ons.
So I went on a mission to find quiet, well performing slip ons. The CVO mufflers have always been the quietest performing mufflers I've seen. Found a set new on eBay (actually a right and left, contacted seller and offered him $150 for both shipped). They arrived Friday and I installed them today. I have three sets of baffles that "fit" the CVO cans and thought I'd play with them all. I also had a set of Ultra CVO cans that are about 3" longer than these.
My plan was to install them and play with baffles. Comparing performance, sound, mpg's. I never dreamed I would like the baffles that they came with. I'm guessing as quiet or quieter than stock. Only a slight performance drop (might just be less rumble) based on seat of pants dyno. Went on a 100 mile ride (around the valley, no highway) and got 42.1 mpg on the tank. I'll do a highway run tomorrow to test mpg's and climbing power (we have a 7% grade that's about a mile long). I can barely hear the pipes unless I get on it, and then it's barely noticeable. I like these slip ons, and I love how they look and are totally inside the bumper.
