They sound great too. There's nothing like watching some lady in her minivan jump out of her skin when you hit the gas

It's like having your high beams auto flash people in front you on the highway...everyone gets out of your way. If you want it quiet and have the NPP, just grab one of those Forza controllers and map it to your homelink buttons. It's been working great for me and you get the best of both worlds.
