So I am not saying I have done this, or that I will, but what would having no cat conveter or one that was punched out do for mgp, and proformence? A buddy of mine was talking about it, and I am curious. I know that modifing the enviorment parts of the exhaust is illegal.
 
does nothing for performance or mpg's, it will actually hurt performance the 4.0 likes a lil backpressure
