The 2 chamber will make more power because it is less restrictive, but is louder. The 3 chamber will make less power, but is a bit quieter because there are more baffles to muffle the sound. Both will add more power over stock mufflers. Personally, I think the 2 chambers are too loud unless you want max power. There is maybe a 1-2 HP difference between the 2 and the 3 chamber.
