Headers and Flanges

My buddy is trying to recreate my exhaust system on his car. He bought a MAC 2 1/2" o/r H Pipe and a set of Flowtech Longtubes, 1 5/8" Primary w/ 3" collectors and 2 1/2" reducers. He wasn't listening well and ordered the wrong stuff. The 3" collector comewith a 3 bolt flange. The H-Pipe has a 2 bolt flange. Does anyone know a slick way of making these work, or is he just going to have to buy a 3" H-Pipe with the 3 bolt flange? I hate to see him waste money.

I'm thinking maybe 3" Stainless!

If it were only that easy. He ordered the stuff from the main land. Price of shipping it back would be outrageous. I told him to try to sell either the pipes or the headers to someone here on island and then order in the right stuff to complete it.
