It comes 2.5" dual 2.5" out but it was listed as 3" in. I noticed the pipe steps up but I dunno if it will step up all the way 3" anyone measured it exactly? I'll measure it on friday when I try to put my 3" intermediate pipe on. The guy at MIDAS wanted $80 because he thougt it was only a 2.5" inlet and didn't want to put the 3" pipe on.
