Not to say that headers can't make a car better but I think what has been said above is pretty much dead on for most vehicles these days.

on my sentra ser spec v, after i installed my header it made quite a bit of differance. install was pretty easy too, which is to be expected on a 4 cylinder. didnt notice any torque loss and noticed a gain in hp. maybe because the stock exhaust manifold on my sentra is so much shitter than the exhaust manifold on the 370z?

I just sent my stillen headers to get coated.
Base line 265. intake, CBE, and cats 292.
Will post dyno after header install.(3 to 4 weeks)

Coated with what?

Yeah because you can buy them ceramic-coated direct from Stillen.

Ya, or just wrap them, eh?

on most nissan motors header gains are questionable, headers are really only needed when you are matching a good set of cams, which for the 370z isnt avail yet.. but a nice custom set of headers or longtubes with a built na motor is the only time i would bother with headers...

Z eliminator · 11-21-2009, 06:51 AM

I got the the headers cerimical coated. I bought the non coated headers and I having them done. I did the same thing for my 350 and the headers still look brand new.

When I dyno mine i will let you know if they made any power.
Im at 291.RWHP with the cats, intake, and CBE. The engine was run to 7500 rpm.

Semtex, would u say that the stillen headers are lighter than the stock ones cause I looked at the stock headers and they looked really flimsy....
