Well...
I can't tell yall how the overall fitment is because the elbo is too big for my setup. I'm externaly gated off of a bolt on. This elbo is actualy so big it gets in the way of my wastegate and can't mount up. I'll have to use my other high flow elbo to mount up the downpipe. It's good for you guys, not for me.
I'm gonna have to enlarge that hole now because the studs on my other elbo won't come out.
From eyballing it though, it looks like the downpipe will fit perfect with the elbo it came with. It aught fit just fine on my elbo also, once I get the hole enlarged.
