I have a simple, maybe stupid question, concerning adding headers to my truck. My headers collect into a 2.5 inch pipe, to which i am attaching my own steel pipe, the question is do i buy 2.5 inch pipe and flare the ends to fit into the header collector and the mufflers which have a input of 2.5 inches, or are there pipes just a bit oversized to fit over the 2.5 inch pipe. Again i am sorry if this is a stupid question.
