I finally found the perfect exhaust solution for my E39 M5! Exhaust cutouts! Huge thank you to Charles at Badlanz HPE for helping me out. In combination with my full Supersprint exhaust (including headers), installing "dump valves" allows me to make the car louder or quieter at the push of a button. Nothing like bringing out the glorious sound of the BMW S62 V8 power house!

As mentioned in my video, here is the link to the install of my Avin Avant 4, where you can see how to run wires from the trunk into the cabin:    • E39 M5 Avin Avant 4 Install (with DSP)
