NC, check the header size on your truck before you buy them. Atleast on my truck, the headers are 2.5" where those are only 2" inlet/outlet. So, you would have to add in some reducers to make it all work.

That was one of my concerns. I have 2" piping coming from the cats back... so I think regardless I'd have to use a reducer on one end.

Well I have 2" piping for a reason. If anything I would keep it the way it is and do 2" piping everywhere still coming out of my 3" tips, or I would switch to 4" tips. It's so loud lol
