each sound good imo

and as said out of the box older subarus, you can even hear the burble, not until you put a wider system with less mufflers as the yanks would say lol

but im oldfashioned and love the burble from a good system on the unequal manifolds set up

So what year did Subaru introduce the equal length headers? Were the Sti and WRX unequal headers discontinued the same year?

Both sound nice, but Unequal just pips it for an Auditory person such as myself

Damn, that sounds

Gonna have to change my pants now made a little sex wee

Yes definitely hasn't been sped up slightly, especially when you look how fast the corsas indicator flashes. Definitely must sound like that in real life.......

Brun

^^^^ Agreed - so real

IMO une-equal length every time! Its the iconic sound I loved growing up watching McRae and Richard Burns.

I tried equal length and now i'm back on un-equal . But hey ho each to their own!

I like both I have a WRX bugeye with unequal headers and a Howard & Scott exhaust and sounds gorgeous in the morning when I start her up !!

My mate has a Type 20 with equal headers and although no burble still sounds nice and then has the power advantage of equal headers!! as well as being a Litchfield Type 20!!

Galifrey

Yeah does look slightly sped up, not by much though, but that would explain the sound. (I didnt watch the video before, just carried on reading posts while I heard the sound).

Errrm you know that the Grp A cars are equal length headers dont you? so you grew up listening to equal length headers

Tony

Brun

Are you sure Tony? This vid has both Colin Mcrae in his title winning car which sounds very un-equal and Rich Burns in the later Impreza which sonds very equal http://www.youtube.com/watch?v=Kpb_k...eature=related

Snap!

I had a 300bhp bug WRX with Prodrive bb, but with deresonated centre and sports cat which livened things up nicely. Sounded great.

I now have a 2006 Litchfield Type 20 (Spec C) with 360bhp. The Litchfields have a Milltek exhaust. In fact it does have a light burble at idle although this goes as you drive off. At low revs around town it's a tad noisy ( but racy! ) and no burble, so the WRX has the edge soundwise when pootling about at 30mph (note the Spec C is a vastly superior car of course). However, when you decide to give it some, it's the Spec C that has the edge - it sounds like a screaming MiMi!

GT Spec Gen 2, you get the best of both.

Slight beat off idle and then the equal scream up top.

im loving that mcrae vid..those scoobies roar, and the flutter from the wastegates sounds like a hamster with its 'nads caught in it spinning wheel

Putting the sound to one side if you guy dont mind what is the best power wise ??????

Benji554

iTrader: (18)

I'm pretty sure the early cars were un-equal Tony. However, I could be wrong, we all make mistakes don't we Tony (2 stroke Harleys)

JohnnyBon, as I understand it:
Equal gives more power at the top end.
Un-equal more low down torque but at the expense of top end power

johnnybon

iTrader: (70)

thanks ben seem like you cant win but is there an middle of the road set up eg:- turbo size to maybe rotated set up i dont no but im sure someone on here will

funkyrimpler

but unequal headers 'makes' it sound like a real rally car..im not interested in top end power..im interested in mid range power and a sound like thunder.

andythejock01wrx

OK, but is there any evidence of that?

The UK Hawks are 2.5s, so to compare only the headers on an equal footing, you'd have to compare the 2.0 blob STi with blob JDM Sti of similar vintage. Don't think the UK has any low down torque advantage.

Andy RB5

You CAN NOT beat the unique muffled tone of the early impreza wrc cars, especially on a foggy Friday night deep in keilder forest, better than any pub on earth I recon...

In theory, could you fabricate an unequal length manifold for a 4-in-line engine and get a similar burble?

arumdevil

sorry I know this thread is old, but...

Yes you can. Old Saab 900 turbos had unequal headers. A 3" catless turbo-back system releases a lovely burble. Not quite as nice as the Scooby burble but close.

Equal length all the way, why have unequal length performance loosing headers? What a waste of time, its an old design and holds cars back, all for a bit of noise which makes everyone that hears you coming think "another idiot in a subaru"
All the unequal length headers look exactly the same, times have moved on and so does tuning!

Me too, when I "nip" down the road that by-passes our village quite a few have thought it was a bike when they've been sitting outside the local pub (which you can't see from the road). Andy

Having driven subarus of many different power types with many different types of headers....

Unequal sound best. It is the classic sound.
However equal can sound pretty good too at the top end.

Equal make for better power - So higher end cars always have to end up going the equal length route. There is a point at when the unequal become a weak part in the set up.

GT spec 2 are the best compromise. As they are for big power cars and have an equal length feel to the sound most of the time. But you can get a bit of an unequal burble low down

JGlanzaV

iTrader: (3)

I would beg to differ, GT spec 2, rcm, japspeed, etc etc etc etc are all the same and unchanged in many years. They are made from poor materials, and hold even lower powered cars back, you can unlock far more from your engine and turbo with equal length. You dont need a high power car to benefit from equal length headers

Putting something on there for a sound is completely pointless in my eyes.

Philip Allanby

This is what a 03 sti with equeal length headers sounds like
If the link works

Steve Whitehorn

Agree GT ect can crack. However Johnnybon asked about a compromise and GT2 spec 2, are in my book. And yes very high quality equal length will unlock the most power.

´´You don't need a high power car to benefit from equal length headers´´
Agree..but my point was at at certain level unequal really become massively restrictive.

``Putting something on there for a sound is completely pointless in my eyes.``
I agree to disagree on that
As part of the driving experience for many is not just about raw performance but about stimulation of the senses and sound plays a big part in that

I was up to 666 on gt spec headers and the car was not restricted at all, so thats just a myth. Will go equal this time as I fancy something different sound wise but not till im over 400bhp
