HELP...OEM Exhaust Upgrades?

Does anyone know the best way to up the noise on the 2009 E92 OEM exhaust? I want to keep the stock exhaust so I'm just looking for something to add that extra roar. I heard of some kind of valve that can be installed but I'm not sure exactly what it's called. Any suggestions?
