The dÄHLer RedLine exhaust system includes a high-flow, double valve controlled, stainless-steel performance muffler and comes if desired with our Valve Controller X with memory and startup mode (only package deal -> select VC2) for those who want to be fully in command of the exhaust sound. One additional original BMW actuator and connecting cable is included in delivery (operation of exhaust valves is unchanged).
dÄHLer RedLine is the most aggressive sounding performance exhaust system that dÄHLer offers for the BMW X3 G01 and X4 M40i G02, yet still provide no drone at highway speeds.

Two matte carbon double round exhaust tips left and right 101 mm / 3.94 inches each -> | Without logo | dÄHLer silver shadow logo | dÄHLer red shadow logo
Our exhaust system for the BMW X3 M40i G01 and X4 M40i G02 (including LCI models) is here to improve your driving experience with an awesome sound and a noticeable bump in performance.
Under normal driving conditions, our double valve controlled performance muffler stays closed (stock), as operation of the exhaust valves is unchanged and the dÄHLer performance exhaust system is quite unassuming. But, when the valve controlled system opens both exhaust valves, the system gives your BMW X3 M40i and X4 M40i that menacing growl.
No check engine lights, no re-programming of your car or anything silly is required after installation of our exhaust system. All dÄHLer exhaust systems are compatible with ALL BMW X3 M40i G01 and X4 M40i G02 models including LCI models and are EPA compliant (USA).
