Cooincidentally, and you will probably laugh at this, one of my friends with a 2006 E60 ESS VT2 Supercharged M5, is going to modify his exhaust system so that not only will the exhaust gases and sound come out of the 4 exhaust tailpipes under the rear bumper, but also so that the exhaust gases and sound are going to come out of the side grills where the plastic usually covers those holes in the fenders with the M5 badge on them. He said he's going to use his local shop here in SD to manufacter new metal side grills as well as design the new piping necessary to get the pipes through each side of the car to reach the side grills. I told him: "That sounds cool man" Lol!
