extractors

[wildturkey]

I've heard I can get good KW gains by upgrading the factory headers on my 89 rs leggy to tuned length extractors.....only prob is it will sound like a honda.....or so I'm told. Can I still get good power gains by upgrading to untuned or unequal length extractors and still keep the subie rumble?

[WRXER]

I personally like the sound of equal length headers, I found they sounded more like an evo and it gives ur car more of a rally sound. The unequal length headers keep somewhat the subie rumble, I currently have a set of these but it still gives it the evo sound once u start flooring it. But at idle etc it rumbles away nicely. Im about to get on the dyno and have retune so can provide figures for it.

You won't get the hugest gains kw atw figure wise with aftermarket headers but it does help free up the restrictions of the stock system in place. Unequal length won't provide you with as much torque as equal length but unless you aiming for a high performace track beast then I wouldn't worry too much over it.

I have tuned headers on my 89 rs rally car.

And at idle it sound pretty much like any other sub. It's not till you give it some and get on boost you notice the evo type sound. But there is still no doubt it is a ub.

[wildturkey]

cheers for that. so many things to upgrade :-)

[WRXER]

Yeah I must agree that by the seat-o-meter it definitely rev's alot faster, especially in the lower range and getting on full boost. I love it. ;D

You should spend your money elsewhere other than on headers...You will fetch better gains by dumping your catalyctic converters and a nice big intake.

They have a bigger performance gain once they have been tuned, but somewhat worthless un'tuned.

[WRXER]

Depends on the debatable description of tuned, it still can be either equal length or unequal length. As technically full tuned ones will not neccesarily be equal length, as it can depend on the engine setup. Good arguments on NASOIC and alike though.

Reviving this old thread:

Looking at doing the old switcheroo on my factory headers to 'tuned length' i.e equal length

I recall Boostin had some EJ25(?) factory equal length headers on his legacy for a while. Whats involved in this swap? i.e non turbo manifold vs turbo manifold= HOW??? I'd rather try go this way as I suffer from studentism and have basically no money.

Sound isnt a problem for me as I honesty Don't care about the sound anymore, I plan on ditching the cannon ASAP as I'm sick of the noise (so are my neighbors and my dog) and I miss the stealthyness. So I'm thinking once I know the HOW it's just one trip to the wreckers and I'm set.

[Guest boostcut]

they just fit up to the up pipe... and id do tuned extractors again. mine sound horny as and you can definately tell theyre on there. its between a mitsi and a lancia, if anyone knows what they sound like

[madmike]

if anyone wants to hear a set in action come to playday on track and hear mine...

Still got rumble at idle but agree with boostcut.. on boost sound like a evo/lancia...

Funny sound. but wicked

[Guest]

Yeah I dont really care either way about sound coz I'm planning on making my car QUIETER, I'm going for more of the sleeper route for my car.

I'm in it purely for whatever slight power advantage I can get out of it and from reading this it seems that there is a slight advantage for torque.

[Guest boostcut]

yeah, i have a 3 dump pipe and 3 inch hks system with just a straight thru muffler on the rear and its too quiet with the extractors on...

[zarnah]

So exactly what model car do we source these poor mans headers from? Mite head to the wreckers and pick up a set, give them a whirl...

[Guest boostcut]

2.5 outback or lancaster... pick a part is your friend...

[madmike]

mine is 3" all the way through 1 small resonator in the centre and a ricer cannon muff at the back.

It's way quieter than mrs sti..

Kinda sad when your Mrs WRX is louder than your racecar :'( :'(

[Guest boostcut]

but you know that wide open throttle is way cooler with the extractors on than standard system!!!

[zarnah]

Im lucky enough to live near ashburton, home of roscos, one of new zealands biggest dedicated subaru wreckers! They are my friend!

Gotta be BD/BG though. BE/BH are completely different.

[dubbedup]

got mine today from the local wreckers today $60 not bad i thought!

[zarnah]

Cool what year are bd and bg?

So in theory this should have the equal length manifold?

+1 , never tell them what you need it for / if you want it as they will see that and up the price... if anything act dumb and they generally feel sorry for ya ;D

for the $150 he is asking I'd look else where you could probably get some cheaper i reckon

[Guest]

Yeah, I didnt even realize that he wasn't in Auckland (D'oh!). Most of that I reckon would be in shipping, and I'm not in too much of a hurry anyway. My health is going down hill so I've cut down my work hours and study to focus on getting well again over modding my car etc.
