A muffler alone won't get you that much gains. Maybe 1 to 2 hp at most to the wheels.

any muffler with a 2.5" inlet and a strait through design will give you the same power. its the catback pipe that will probably make the most diffrence. if you go with a mandrel bent pipe go with 2.25. if you go with a non mandrel bent pipe go with 2.5"
