Been looking into getting some, what benefits will i get? As i dont want to loose the Subaru Burble
And secondly isit a big job to do?
Cheers in advance Matt.

 

Anyone????

 

ul keep the burble as they are unequal, if u only change headers is a easy job, ul see them under car, 3 bolts per head and 2 two joinning them to up pipe. they will help spool up on turbo, id recommend doing up pipe same time for better spool up results. up pipe is more difficult to change

 

does it then require a remap ?

 

where do they supply a good set of headers and up pipe what everyone else using i no u can port them but what u pay porting them u might aswell buy some

 

yes

 

Yeah i was wondering which are the best to go for?

And thanks for the other replies

 

What about this one?
Subaru Impreza Stainless Steel Tubular Manifold --- Japspeed Performance Parts

 

HKS, gruppe-s are the most popular ones

 

I had ScoobyClinic which I thought was a great improvement over standard, I then changed to a set from Lateral Performance, far better than the ScoobyClinic. Spool up on my MD312T was very much improved and the noise on full boost is awesome!

 

i have japspeed headers and up-pipe.both lagged with exhaust wrap and made loads of difference to spool up etc.still have the burble.

 

I have some 2nd hand RCM ones for sale from my 03 car. No up pipe, just the headers. Has a slight repair, but work perfectly if anyone interested.

 

Are they a good fit? Have you lost any of the burble or has it stayed the same?

 

they fitted perfectly and only took an hour or so to do.got all the gaskets,bolts,nuts etc with the headers.still have the burble up to about 4 grand then it smooths out and sounds like a big bike.made loads difference to the car as spools up so much quicker.also make sure you wrap the headers and up-pipe to help with spool up.

 

That's great buddy thanks for your help, did you go the headers I posted a link to?

 

hi mate, i got those but the equal length ones and very good quality, nice tig weld, mandrel bent...also got uppipe...they're all flexi ones so it's better

 

Awesome buddy thats good news as theyre uber cheap!

 

Good = cheap

Bad = no slip joints in cross pipes, flexy joint is bad too !

IMHO

dunx

 

hmmmm interesting wonder what other peoples thoughts are on japspeed headers then

 

i got the ones from the link and was very happy with the quality and fit and their a good price as well.just spent £30 for the wrap from sorenson road sport (30 metres).

 

Thats good enough for me plus im not paying the mrs is

 

cheers simon,(bit belated sorry)

 

I just started off with decent ones in the first place, you get what you pay for really

Tony

 

What do you have then fella

 

well they are good for the money and not everyone wants to spend silly money on their car.£200 is a good price compared to ebay etc...
i gained 39 bhp from hks system and the headers so they must work as well.
each to thier own and these headers are a good starting point unless your going to be one of the 'i have 450 bhp lot'(have driven a few big bhp cars and they are awful on normal roads.300 is plenty just add big brakes and suspension and beat them in the corners.

 

Im gonna get to 300-320 and see how i get on and take it from there, mines got stock sti suspension and the pink sti rear arms so handling is already pretty decent just need some good tyres

 

the best headers I have used, seen etc are the headers that Mark @ Lateral sells..

both with regard to spool and power and reliability..

Cannot comment good or bad on scoobyclinic headers as don't recall examining any.

Simon

 

H&S GT spec not exactly cheap but very good quality

Tony

 

my concern with these and it maybe unjust.. is that they look a similar construction to the megan headers which blow on the flexi joint and around the collector area just before it.



Also there is no slip or flexi joint between the manifold run to left bank and collector.. so any expansion of the manifold will be causing stress on the collector area etc..

Very interested to hear from anyone running them long term to see if they are lasting well.

Simon

 

agree the H&S headers are very good
