Mufflers, Cams, Carbs.... it's all this same. The same in that there isn't any ONE of anything that is gonna be just what everyone is looking for. As for myself everything I've heard about the Vaporizer is good!! It sounds perfect for my situation, I'm in the body work, paint and upholstery phase now and a engine rebuild with power mods could be years away. So until then I'm stock under the hood so the Vaporizer is a dream come true......I'm just a payday or two away from getting one. However if anyone out there ever does do a tri power with three Vaporizers I would love to hear about the results.
