output flange for T3 Garrett to build downpipe

One of the last things I need for my turbo swap is a downpipe on my 244. I have a Garrett from a 240 turbo but I didn’t get a downpipe. I’ve been looking online for just the flange for the output side so I could build a downpipe off of it but I have had no luck. Is this something I should go to an exhaust shop to have them make a flange for it? What have people done when they need to make a downpipe? My T3 is a 3 bolt conical pattern. Thanks and I hope I put this thread in the right location.
 
Sent a message about that pipe but didn't get a response. From what I have been looking up I saw some information saying that the pipe from a 13c would fit as long as it is a 3 bolt pattern. Is this true? I have had no luck finding any pieces that would actually work. What have people done who have made their own downpipes? Bring them to a shop? I don't mind welding a pipe but I can't seem to find the flanget that would work.
 
I believe that is true. The same way the bolt pattern of the manifold is the same. I never tried to switch from a T3 to a 13C, but a 15G can replace a T3 without any flange problems.
 
Yeah it's called the conical output flange and they are all the same volvo wise as long as they are conical flange. Only 15g that is conical is the early one, later ones are flat flange. That ebay link those look like flat flanges, not conical is similar but not flat. Flat flange is flat to flat, conical the dowpipe flange fits over the turbo hotside output at an angle. Not flat.

Here is the conical the one you need.

Here is the flat, see it's flat but has a step so no gasket needed.

Are you doing a 3" downpipe or just stock replacement?

I have a stock flange I could remove from the stub and get to you cheap.

I also have two 3" starter kits left if going 3"

Thanks for the links! Those look good if I go that route
