I forget where I saw this, but apparently pipes marked with E4 are built to the new Euro noise standard, which means they will change the tone of the bike, but not necessarily make it much louder. So for anyone who's concerned with installing too loud of a pipe or being a good ambassador of "the sport", that's always an option.
I'm in the same boat. I don't really want to make my bike a whole lot louder, but I would like to get a deeper rumble. The weenie sound of the stock pipe is a bit annoying.
