First of all, as an owner of HD's in the past, the Wing will never, ever, sound like a V-twin. However, if you are willing to spend $0 and some change and 10 minutes of your time, this may be for you to add rumble to your bike. Take off the (3) 8mm bolts (each side) and remove the exhaust extension. I started off by drilling a 3/8" hole but went with a 1/2" hole. Put everything back together and you are done. It's also a snap to put it back to stock if you don't like the sound by using freeze plugs or threaded pipe plugs with JB Weld. Mine sounds as nice as my friends Wing with Cobra's. My preference is to not use any exhaust which deletes the catalytic converters. I hate the smell of unburnt exhaust when riding in a group and pass the first bike that smells bad. The reason I did this mod was because I ride fairly aggressively and missed several shifts because I couldn't hear the engine. Good luck!
