Its the easiest and quickest way to remove headers or pipes. My father in law welds a inside sleeve in the header collector that the front pipe slips over..no leaks that way. I don't do it because I'm worried about the pipes "sticking together" over time. Plus I don't want to take away inside diameter.

Exactly. I've slid them together with anti seize and a band clamp but after a couple years they still seize to the point that I have to apply heat. Then the system is discolored.

Rather than use the actual 3 bolt collector pieces to make a flange, and then have differing or odd looking sizes between pipes and collector....I simply just use a 3 bolt flange itself, and weld that directly to the pipes for a cleaner appearance that appears like one joint rather than 3.
