Big block HP manifold down pipes

[Sly_drums]

Hello, I'm searching for a pair of used or new big block stock down pipes.
My 383 currently has Hooker headers and a 2,5 inch dual exhaust linked to it, but I want to go back to stock HP manifolds (no more clearance issues and I like the stock looking of them...).
I just bought a pair of them but now I'll also need a pair of those down pipes/flange pipes to connect the manifolds to the exhaust pipes.

I don't need the exact matching parts but only the parts that connect to the manifold and go down. I know it will need soldering here and there with additional tubes to match the current exhaust.
Do you know where I can find such parts ? Used or brand new ?
Thanks

Try Accurate LTD....you might have to buy a set of headpipes. Actually I know TTI sells just what you need, but I'm not sure if they have them in a "stock" size.....worth looking into.

Thanks Anlauto, I just sent a mail to Accurate LTD 
TTI don't seem to have the "stock" sizes.
