I've an '01 h/o 6spd with just an edge ez and a 4" strait pipe and my dad has the same identical truck as me but he has the adrenalin on his with an airdog 150, and by the seat of the pants my truck pulls harder on the bottom end then his. i'm thinking about stacking the smarty with the ez on my truck is this a good combo?
