Hi guys,
I have successfully retrofitted an AMG performance exhaust in my Mercedes GLE 450. Originally my car had two exhaust outlet pipes (the right one with the actuator ) looking down and blind end tips in the bumper. I have retrofitted the GLE 53 diffuser and complete exhaust with an end muffler. All is almost bolted in except you need to modify the rear heat shield.
To control the actuators after modification you will end up with two of them one on each side. GLE 450 has no button on the center console for opening /closing the flaps.
I have used the ASR (from asr-comonenet.de) module with a remote control. ASr performance selling them for various Mercedes models. It has a harness to connect between the original actuator and the car. However, I have chosen to mount the module inside the trunk so I cut the plug and socket and soldered the module between the original wires ( see photos ).
All is working like a charm, I can control the flaps whenever I like or keep in auto. The sound of the engine/exhaust is much better. I have no 53 to compare with but based on yt videos sound is the same now.
