ok so that answers the question of power. does it mess with your back pressure? and the midpipe was the section that i was referring to but it seems you already knew that and possibly have something in the works for that. I just found it unclear as to why you where going from one size to another back down. And as i stated in a previous post that the product looks very nice and well engineered and built. The welds are very nice i just couldn't convince myself to eliminate mufflers to a 3in pipe but still run the stock piping to it.
