First off let me say I have first hand experience installing this similar exhaust on my car. Let me ALSO state that I had this "fitment" issue. It's not a fitment issue, rest assured; take your time. They don't need expansion, you need to insert them directly in and Straight. Have a friend help hold them as you do so, in fact, twist them together and straighten after. I'm telling you this now before you pay someone to expand the pipes!
