BBK headers exhaust flange

[jwestra]

hello,

I recently bought a set of BBK headers for my 4.0. They did not come with the y-pipe so I am just going to fab one myself but I can not find any exhaust flanges for it anywhere. The inside diameter is 2", I haven't taken the stock y-pipe of the truck yet so im not sure if those will fit the BBK's I've searched the forum and came up with nothing so I figured ill make a thread and see if someone can point me in the right direction.

Thanks,
Jacob.

I have BBK headers on my truck...Mine came with the downpipe, but it needed modification to fit correctly. The downpipe-to-cat flange that came on it was the 90-94 style, even though they were designed for 95-97 model years. I went to the junk-yard and got a spare downpipe and cut it up and used the downpipe-to-cat flange and pie-cut each pipe until they fit into the flange and welded it all similar to the factory setup. I do believe its 2" pipe if memory serves me correct.
