Installing Extractors/headers

[Nights]

Hi guys,

Just snagged myself a nice set of fujitsubo extractors/headers

Now, from what I can tell, the heat shield on the stock manifold protects heat rising up and heating up the plastic intake pipe, and the resonator assy.

(While im at it, could someone clear up what the purpose of the resonator assy is? The big box thing on the main intake pipe?)

Anyways, back to the point, putting on the extractors is going to mean the heat shield is gonna come off, cos it wont fit over them.

They are stainless steel, and arent coated in any heat proofing, so im thinking this could possibly cause the intake air to heat up, or melt the plastic on the bottom of the resonator assy? Heat shield is obviously there for a reason.

Im just wondering what anyone else with extractors did? Even better anyone with fujitsubo ones. Did you just install them with no heatshield? Or did you mount the heatshield higher up on a custom bracket or something?

Im guessing most people got their heat proof coated, but id like to avoid doing that if possible, i like the stainless steel shiny look.

you can buy sheets of ACL heat shield from superrepcobarn, make some up if you want.

Cheers Zebra! That sounds like a plan

no worries,

post pics of the headers when done

per Zebra's advice regarding new heatshield. If youre heaps anal, you can heat wrap it too.

And this resonator thing? Im going to take a guess and say you have an NA R34, with the neo RB25? If so, dont worry, it means nothing. On a RB25, an intake pipe is an intake pipe, a local NA r34 ive seen around has replaced his with a metal pipe, no difference.

Normal driving It doesnt really matter tbh, but as soon as you head out to a time attack day and give your car hell for a few laps this happens.

Have aftermarket extractors, have been in for about 2 years with no problems to be had until the track day.

Not coated with anything and have no sheild.

That resonator box is a part of emmissions. Intake noise emmissions that is. At certain RPM points the engine can and will make different sounds. Whether you hear it or not is another thing.

So you're the guy who won those extractors on eBay. I wanted them so bad!

It must be you because these things are fkin rare and if I had the money to spend I would have bidded even higher!

Let me know if you ever decide to get rid of them.

Chuck up some vids when you're done, I wanna hear how they sound.

Zebra: Will do

Nismo: Nah ive got an NA r33 with an RB25de. But Im guessing i could change it over to a metal one without too many problems

Two Cents: Thanks! Thats precisely what i thought might happen. Cheers for the insight.

MBS206: Oh, yeah i figured it had something to with sound, couldnt figure out what though. Cheers for the info!

Jimmy: Haha!! Yeah it was me! Damn, yeah the things are rare hey! Yeah if i ever decide to get rid of them, ill let ya know.

Hope another comes on ebay for you though!

Yeah ill do a vid, might be a while though, have to get an exhaust to match and currently working on changing water pump and painting calipers.
