Notice some tea leaf has nicked the right hand box in the last pic..dual exit boxes can actually be detrimental to flow on a modded exhaust box..but if your not worried about the performance aspect [of which there will be little anyway from a cat back] then why not ..whatever floats ya boat..

how much you looking? lovein the look of the quad exit mate

Had the option to do that when I got my system. Saw another Stilo that had had a dual exit done so as they were pointing out the edges of the bumper. Looked quite different, but personally I wanted something simple but purposeful looking.

Still though, this system does look rather good.
