Muffler Tech 2014 E63 dual mode exhaust

This is our remote controlled dual mode exhaust all operated through the vehicles Homelink buttons on the bottom of the mirror. One button opens the exhaust to a straight through X-pipe setup and another closes them to route the exhaust back through the stock silencers, with this system even through the stock silencers (valves closed) it is a little more aggressive than stock as we eliminate the center resonator to make room for our X-pipe. Enjoy!
