Steedspeed billet exhaust manifold.
Anyone with experience with this manifold? Just wondering how well welded billet steel works with diesel exhaust temps. It's a one piece manifold, would there be a problem with the expansion rates of the cast iron head and steel manifold?

The installation was pretty good. I installed it with the turbo on it so it was a bit of a pain but that was mostly due to the weight. If it would of just been the manifold it would of been a breeze. I used the factory torque specs I think its 35 ft/lbs. I just checked them yesterday and there all still good and no exhaust leaks. The black coating is awesome it looks just as good as it did when I put it on and its seen +1500* quite a few times. It seems like the coating works pretty good, it doesn't take to long till the manifold is cool enough that I can work on it, the stock one took forever to cool off.

Hopefully soon here I will get back on the dyno. The dyno shop has just been swamped and I have been getting busy with work so things just haven't worked out. It definitely has more usable power though as it spools faster and I can stay in it longer without the egt's getting out of hand.
