BMW's M Performance Parts
Naturally, BMW likes to get in on the party of souping up their own cars, and they've just presented their newest lineup. The things you'd expect them to have are present—power boosting technology, suspension upgrades, sporty flare, etc. There's also the always-gorgeous BMW Performance steering wheel with the digital display that's been updated to fit the current lineup, but the real showstopper is the exhaust, with bluetooth-activated valves to control how loud you want your car to be.
