jerseygator Posted February 26, 2011 Report Share Posted February 26, 2011 Was cleaning my undercarriage this winter and noticed some black carbon/sooty stuff around the back of the cans. Close to the bottom of the seam. Upon further inspection it looks like there is a pin hole in the muffler. They are only a few months old! I'll be calling my Ford dealer next.
