BMW X4 M40i dAHler Performance Sports Cat-Back Exhaust

High Performance dAHler Exhaust System For The BMW X4 M40. Rear Cat-Back System With The dAHLer Dual Valve Control System & Carbon Fibre Exhaust Tips!

A dÄHLer exhaust system for the X4 M40i fits models before as well as LCI models and comes with a high-performance silencer with four outlets and one additional exhaust valve with a much more aggressive sound then the stock exhaust system but still be perfectly livable for daily driving.

The system includes a high-flow, double valve controlled, stainless-steel performance silencer and comes as standard with the impressive dAhler Valve Controller X  to give you full control of the exhaust sound. As well as the impressive stainless steel system this setup includes 4x Carbon Fibre Exhaust Tips in a variety of different options.

Under normal driving conditions, the valve-controlled system stays closed, and the dAHLer performance exhaust system is quite unassuming and nobody will really even suspect your car even has an aftermarket performance exhaust system. But, when you open up the throttle, the valve-controlled system opens up the exhaust flap, and the performance exhaust system gives your X4 an impressive, much more refined sound (That it should really have come from factory with).

One additional original BMW actuator and connecting cable is included in delivery (operation of exhaust valves is unchanged).
