A dAHLer performance exhaust system comes with a high-performance muffler and valve control system with no drone on the highway of a much more aggressive sound than the stock muffler but still be perfectly livable for daily driving.
No check engine lights, no re-programming of your car, or anything silly is required after installation. Approved and tested by the German TUV this system comes with a European Homologation according to the latest emission standards and is EPA compliant (USA).
Not only do we engineer our valve-controlled performance muffler to sound good we engineer the BMW X3 M40i / X4 M40i exhaust systems that fit your BMW properly for a much easier installation.
Designed to mount using the factory exhaust hangers, the system is a bolt-on replacement for the OEM version. To help reduce the time you spend installing the dAHLer performance exhaust system on your BMW X3 M40i, slip-fit joints are included to make fitment as easy as possible. Our quad exhaust tips with a 101 mm (3.95 inches) diameter are designed to fit the stock BMW diffuser perfectly.
The dAHLer BMW X3 M40i X4 M40i exhaust includes a high-flow, valve controlled, stainless-steel performance muffler, and is available as an axle-back system.
Our performance exhaust system is here to improve your driving experience with an awesome sound and a noticeable bump in performance.
Under normal driving conditions, our valve-controlled performance muffler 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 our system gives your X3 a menacing growl.
For those who want to be fully in command at any time, we developed our Exhaust Flap / Valve Control Module with remote control. It operates at the push of a button on the in-delivery included remote control and can be successfully programmed to the mirror buttons of your car.
