Any increases in fuel efficiency or overall HP? It's got to be breathing a lot better!

I assume that u cant legally just remove the cat?.... I mean why not y pipe it?

[@1rebel13]

I can do whatever I want. It's already h-piped. I kinda like the stock box. If I where to do it again, I would also debaffle the can.
