Is it just me or does the 997 & maybe other 911 models chuck out a load of carbon deposits out of the exhaust pipes. My Cayman's pipes used to get dirty but only required cleaning about once a week however on the 997 I can be cleaning them daily and as it's a white car it also leaves deposit's on the rear bumper. Maybe I'm a tad OCD but I do like the pipes to look shiny and the bumper not to be covered in tiny black dots !!
If not could the car be running a bit rich ?
