I drove mustangs for the better part of my driving life and one of the best bang for the buck was an offroad (catless) H or X pipe (back when an inspection was easy). I would love to throw one on and see the difference but I understand it will throw a CEL unless tuned for it. I guess now the "on road" high flow cats are probably good also. If I was running a tune an aftermarket down-pipe would probably be next investment and keep the stock one just in case.
