I got my first Steed Speed 11 years ago and it’s very hard to even want to look at any other manifolds after having one of these works of art and seeing how amazing the quality is. How the ports are beautifully smooth unlike every other cast manifold out there, and how easy it is to option one out to do whatever you’re doing with your truck.

Best looking manifold. Love the coating so it won’t rust like alot of others.

It’s the only manifold I’ve ever dyno tested and seen power gains consistently. 3.0” smooth bore is about 40-50 hp over a regular log cast manifold. Street trucks vary depending on turbo set up.

I have 2 for 5.9 cummins, my only complaint, you don’t make one for a series 60 detroit

No more exhaust leaks between the joints and such a nice work art

I went from a stock manifold to your T3 and I could honestly feel a difference in the truck. It ran much more efficiently, and I could tell a difference in my EGTs. Not to mention it cleans up the engine bay opposed to an old rusty cast manifold. Only exhaust manifolds I’ll run!

I love it! Fantastic choice. It just freakin works. Industry leading for a reason. If you’re gonna make me chose a downfall it’s gonna be that I had to send it out to be nickel plated 3rd party but that didn’t bother me a bit and I know you guys are exploring the option just waiting to see how they stand up.

Wanted the best and to know I would never have to replace it. It’s just a shame to hide something that looks so good under the hood.

Likely a key to success for running a big single on my 24v vp44

It’s great, I will never buy anything else!
