Yes, they fit with the stock shields. Yes, in my opinion, the plugs I installed made them "un-obnoxious". Also, the stock baffle is still installed, so if you wanted to quiet them down further, you could insert V & H Quiet baffles. The regular baffles don't have any wrapping around them.
These came off my '98 Wide Glide. Total mileage on the bike is 8,000 and these weren't always on it. A picture will show one scrape from leaning over in a turn. It's on the bottom obviously, and not very noticeable. The scrape is smaller than my thumb. The overall quality is very good. The chrome slip-over cover is very nice. The baffles included are standard, and I also installed Smartparts quiet baffle ( a plug insert - $69.00) into the baffle at the end. You can remove it if you want it louder.
