Does anyone have a 4" single shot exhaust that exits behind the axle? I plan to have a custom 4" aluminum system made for my Buick but am not sure if it will go over the axle or not. I've seen some guys run it under the axle but that seems awfully low. I want it to exit in the same location as the ATR single shot that I used to run which is behind the passenger rear tire. I may go to 3.5" if 4 wont work. Any pictures would be much appreciated. Thanks
