So , im extremely new to this forum , but I have a question that's really been daunting me . Maybe someone can help . Own a 2011 BMW 328I Xdrive , still haven't figured out the chassis codename yet , which makes this task even further diff , but I hear you can disconnect a butterfly exhaust valve switch located in the rear trunk , driver side , pocket wall ? Ive looked several times high and low can't find switch to unplug , aside from tail light switch Any help , is this even possible on my model or do I need to just replace exhaust ? Would like to gradually start building my baby into the " Ultimate Machine " !!?? Sorry , if Im not posting in correct side of forum . Thanks in advance !
