M4 Racing Exhaust

This part is listed by BMW as BMW part number 18302349921 (18-30-2-349-21 ) and is described as BMW M Performance Titanium Exhaust for F80 M3 and F82/F83 M4.
This is it -- The authentic M Performance exhaust designed by BMW engineers for weight, performance, and sound. If you are purist who only wants Original BMW parts on their M3/M4, this might be an exhaust that appeals to you.
While we several high-end exhaust options for the F8X M3/M4, this is the only Genuine BMW option (besides stock) available. This system retains the factory-style exhaust flap control system, so that around town -- with the flaps closed -- the system is much tamer. But under full throttle or heavy acceleration loads, the flaps option to let the beautiful twin-turbo 6 cylinder symphony sing, with lots of fun popping turbo sounds that make the hairs on the back of your neck dance with glee.
The M Performance Exhaust comes without any exhaust tip finishers, so if you want either the titanium exhaust tips (as shown in the photograph) or the carbon fiber exhaust tip finishers, be sure to order four of them along with this exhaust system. If you like the look of bare titanium tubing, you may enjoy the look of the exhaust without exhaust finishers, while some like spending the extra for the perfect tip styling.
Please note. This exhaust is too large to ship by standard carriers such as UPS. It must be shipped by truck freight. We will email you with a freight quote upon placing your order.
