It can hurt gas mileage, which may cripple performance, but not likely. I would replace it if you are doing the exhaust, but I wouldn't replace it for performance gains. To make it idle smoother, maybe you need: new plugs, rotor, cap, wires, clean fuel injectors/replace. Being a 12A owner, I'm not that familiar with all the little "tricks" you can do to the 13B, but those suggestions are some basic things you might want to check out.
