Can these flanges be right?

I have here new Ram Air Manifolds - I ordered them from Butler. I got the downpipes from Ram Air Restorations - they also told me to buy a set of flanges tat are needed.

I laid out the manifolds and downpipes to get a look at how they'll go together, and I'm really unsure about it. The downpipe has a flange on it, but it's also expanded at about the last 2.5". The provided flanges can't get anywhere near where the connection is made.
It's hard to explain, so I just made a quick video.

Take a look at this - am I missing something, or is that pipe expansion at the end not supposed to be there??

Damn.... Ockham's Razor.... I was spending all that time trying to figure out how the flanges should attach when it should've occurred to me...they're just too small!

Thanks man -

As it turns out they are the right flanges.... with the wrong downpipes!

I spoke with Paul at Ram Air Restoration - he was very helpful. He knew right away there was a problem - you cant put downpipes for a Chevy big block on a Pontiac. :-)

When I ordered the downpipes I ordered the "SHC" instead of the "SHP." Well, guess what that "C" stands for??

I'm shipping back the pipes and Paul is getting a proper set ready for me...

As I say every day in my line of work.... User error!!

Glad to hear that things will be getting straightened out for you, I've heard Paul is a good guy. Best of luck with the installation!
