I don't really have anything to compare it to. I just left what was on there, on there. Bike had those muffs, but there was an exhaust leak so I pulled them off. That's when I saw the HD writing. Googled them and found out they came from a sportster. They had holes for crossover tubes which were leaking. I took freeze plugs and hammered them down over the holes to stop the leak. Then I put some JB weld (best shizzle since duct tape) around them to prevent pinholes. The whole exhaust is super ghetto- the PO has it held on there with friggin hose clamps. I'd like to replace it at some point, just have no $. I'll see if I can post some pics tonight of the fabulousness.
Oh, and it was farty, too, so when I had the muffs off to repair the leak I shone a flashlight inside. Turns out the PO had drilled holes through the baffle thingy in the middle of the muff. There were raggedy bits of metal hanging off, making a farty noise through the pipes. I punched the rest out and smoothed the metal down- no more farts.
