It’s prettier, that’s probably about all. You need to route a hose from the breather that will prevent oil from getting on anything important, like brake pads or tires. I ran my SS breather hose vertically and put a K&N breather on the end. If I did wheelies on purpose I’d probably have routed it a little differently, but I get no oil out of it. On other bikes I’ve routed the breather to puke on the chain.
