so i need to know what size or were i can get some collectors that will fit the stock 6.0 manafolds.

When I put my AS&M's on, I used 2.5" gaskets. Had to cut and weld new flanges in front of he cats, but that's the pipe size.

 

The stock manifolds have a goofy flange shape. I don't think it will use any of the standard collector flanges sold. You'd probably have to trace one of the stock manifold flanges and cut it out of a piece of flat steel stock.

I think that is what you are asking about.

 

hmm that sucks there has to be some offered somewhere.
