Steedspeed 3rd Gen exhaust manifold...
 

Just got mine on order.... Nice piece.

I'll be getting one soon too. I've been anxiously waiting for this to come out.

Yeap, finally a real real nice piece to make me want to spend the money.

Torn between this one or the "STAINLESS" diesel one[duhhh][duhhh][duhhh]---both look like quality pieces---Steedspeed is a bit cheaper though.DW:cool:

In pics 1 and 2 you can SEE how the ports run to the flange before the billet halves are welded together. He is also in the process of making a "drop in" 6.7 version.

Moment of weakness---spent my overtime $$$$[coffee],ordered(STEEDSPEED) one up tonight.DW[guitar]

AS PER Leen Steed email---back ordered until late next week.Hopefully a early X-Mas gift.

Is this jut a cool piece, or does it have magical HP?

Bit of bling:cool:,hopefully give a bit more HP(as per the posted dynorun sheet on the there website), cool EGT /better flow/quicker spool---similar to the 2 and 3 piece designs out there but in one piece.It may be tuff to tell cause a HTT 62/65/13SS will go on at the same time.DW

I am just doing the manifold. That's it. I am looking for the torque gain at 2000 rpms where I tow. On the dyno sheet you can see an increase of 143.24 RWHP and 378.55 RWTQ at 2000rpm's. I do have a the Hamilton 188/208 cam so we will see what I get.

When will you have it?
Make sure to post up your findings!

Couple of more weeks. Won't be able to dyno, no dyno in my area. So, the butt dyno it is....

"On the dyno sheet you can see an increase of 143.24 RWHP and 378.55 RWTQ "
Really?I can barely read the #s but a manifold aint gonna give you anywhere near those figures.Maybe the decimal points are off,like 14hp and 37 tq?

Thats the way i'm thinking too-----but any little gain is better than stock manifold.

Total HP/TQ gain is that low. I am looking at what is under the curve, the usable HP and TQ. I don't use my truck a peak HP and TQ.
