Default converting a slipfit header to 3 bolt
I know i have seen this for sale somewhere.. it about 4 to 6 inches of pipe and it slips over the collector and has the 3 bolt flange on the other side

Why not just get a 3 bolt flange welded onto the end of the header?

Slip-fits are better anyway.

A good slip fit and a band clamp thats tq'd right works like a charm. I just swapped back to slip fit after 3-bolt.

Slip fits seal better (IMO) and give you more ground clearance and flexibility while installing. It definitely depends on the quality of the clamp though.

He speaks the truth, I was about to cut the flanges off of my lt's before I sold my car because they scraped the speed bumps going to my job every day.

I will take a proper fitting slip fit any day. Three bolt flanges warp, leak, blow gaskets out and reduce ground clearance.

Band clamps, try this link should work for what your wanting. You'll need a couple of them.
