I have a roommate with an 04 4.6 SCSB. He wants some shorty headers nw because a buddy of ours has a new king ranch 5.4 with JBA titanium coated headers. We felt the performance and it was like night and day! Is there a less pricey header, that is ceramic coated out there that will get my roommates anemic 4.6 a kick in the ass. He has a flowmaster muffler, k &n filer, and a diablo predator tune. His truck is SLOW!!!

Ya THINK???? :jest: sorry I just could not resist!!!

Is this a new or old bodystyle? I'd have to check, but I think I might have some Pace Setter shorties that would work, altho they're not coated. They're for a 5.4, but the heads should be the same.

FWIW, the big difference in performance would be the extra displacement, not the headers, lol. The stock manifolds are good for around 500 RWHP. The L guys have proven that beyond a doubt.

hahaha. It is SLOW!!!!! Those sudden stops will kill you though. :lol:



Those manifolds can flow that well. I saw them and the collecter is only like 2" in diameter. How can that support high horsepower? My roommates truck is the NBS (04')

I dunno bout the new body style, but with the 97-03, the biggest restriction in the exhaust sytem was the stock cats. Look under his truck. If you see 4 cats (2 small, 2 big), then that right there is power you can find. Look for highflow cats/midpipes.

And it should be 2.5 out at the manifold. Don't get me wrong, a set of longtubes won't hurt anything, but there's other places you should look first...

If you are gonna do one, do both. High-flow cats (or none at all if you can) will make a difference. So will a decent set of headers. The cast iron manifolds, while not terrible, leave much to be desired. The stock manifolds may be good for 500+ rwhp (I know of a few at 600+ w/ stock manifolds) but there are good gains to be made with a good, non-interferance design header. Pacesetter offers some nice longtube headers now with matching offroad midpipes. They just finished the fixtures for them and they are now shipping them. I bought mine through Jet-hot...fully coated inside and out.

Not to take anything away from Pace Setter ( I have a set of shorties from them ), but if he want's LT's, look into Dynatech's. Easiest installation out of all of them......

Already lined these up....they will not be difficult to install. Dynatechs are certainly not easier and are $500 more. Can't even compare them on that basis as the LT's from Pace Setter have barely hit consumer hands. They only finished the fixtures for production 2 weeks ago.
