If you decide on side pipes and your wife or grandkids (any kids) ever ride with you then at some time in your future you will be dealing with a leg burn or worse, and the scar from a good exhaust burn stays with a person for a loooong time. I've cooked my arm a couple of times on my lake pipes, and I really worry any time a kid gets near with it running, or recently shut down. They will heat up enough to cook flesh to medium rare within thirty seconds or so, and hold the heat for a few minutes after shutdown.
