Who stocks Steed Speed Manifolds

I am building a new compound setup for my 2016 2500. I need the wastegated T4 manifold. What I can't decide is should I use the straight flange or the angled? Do the angled flanges work okay with the wastegate? It seems they would work better with the angled flanges? I plan on mounting my S480 where the battery was and running an S369. I do occasionally tow my camper with my setup and am shooting for 1000hp. I am at 830 now.

Check power driven diesel. Not 100% sure but josh macrrmick just post he got one through them and they stocked them.

Thanks and I just looked and he doesn't have the one I want.
