Once again I ask why? Even looking at the pictures of the pieces out of the box makes even less sense of why someone does this. Do you think that 1 foot long "elbow" piece that MS uses has some advantage over the stock elbow? Other than that its simply a drop in filter which you can do anyway. Just do not get the thought process.
Just makes zero sense. Sometimes I get mods make our car personalized but this seems to have absolutely zero utility for looks (considering you said it looked stock anyway) or performance. Do people really like to just throw away 400 bucks for fun these days?
