OBX headers and uppipe
I have just fitted the above with both my hks fmic and apexi induction kit. What i have found is that although there are no leaks in the full system (TSL open neck downpipe, H&S unresonated centre, Ninja backbox) the headers have changed the scooby burble i so love into a loud rasp much like an evo.
Any thoughts?

I heard the main benefit of the equal length is a gain in power but you lose some of the midrange torque the unequal length gives you is this right?

I am not going for running boost yet as it has not been remapped to accomodate the headers, injectors or fmic yet. Hope to very soon.
Starting to like the sound btw!

Think i'm gonna have H+S make me one up - but it's nearly the cost of a new set of OBX Headers!

got headers s/h - thinking I can just buy an H&S up-pipe to fit (would have made them a bargain) - then found out when delivered the up-pipe has a 90deg bend in it - meaning a "standard" H&S up-pipe would'nt do the job. Fair dues to the chaps at H&S - they are extremely helpful - just gotta persuad everyone to put towards the up-pipe + *******isation to fit as a christmas present (i.e. because its a custom job it is more than the standard up-pipe) - meaning they were not such a bargain price - DOH!

Is the noise of coming off the throttle even with a recirc. meant to sound like a a big pssssshhh like you have in films like F&F ?

I have a Type R - so that makes me want to fit them YESTERDAY - just gotta save for th up-pipe!
What difference do they make to driveability (i.e. much more top end punch etc?)

when you getting it remapped?
I would imagine that some more fuel will need to be mapped in?
From the description Scooby_si gives, I am REALLY looking forward to fitting them - esp. as I have the 8K Red line as well (mated to a Blitz Nur SPec r - should be sweet!)
Dont suppose anyone can take a sound clip and host it?

I will try over the weekend to get a clip of the sound and put it up/send it to you.

Bugger! Hope you can sort it OK - 550's are my next port of call - running about 310bhp so maxing out the 440's - are they a difficult mod, or fairly easy to fit?
Ordered an H + S up-pipe today - so getting there! After finding out we ARE getting a healthy bonus, I will be able to afford the modifications to th up-pipe!
Wonder if Scooby-si managed a recording!

obx are fun @ the top end.. altho you might find that you dont get to really stretch its legs often enough..
i had OBX and went to gruppeS..
prefer the sound now tbh with my lo0n modified hiper..was too tinny with OBX., and the low down driveability of gruppeS is nice.
Altho I sometimes miss the insane OBX scream @ 6k+
bearing in mind that 6k+ is lo0ny speeds in nearly every gear.

Gutting up-pipe
A job I want to do , but don't want to waste my time if the up-pipe on my MY99 does not have the catalytic converter in.
Can anybody confirm whether it does or not?

MY99 up pipe has no cat - the only cats are downpipe and centre section!
Chrome, I have a Type R that likes to scream its nuts off anyways, and I wouldn't have thought anything will sound too tinny with a Nur Spec R on?
Out of interest, what driveability differences were there between OBX and Gruppe S?

Cheers, when you say more mid range with the gruppe s, i assume the OBX do not detract from the standard mid range torque (im hoping they add to it - even if not as much as the Gruppe S ones).
Just got my standard fit H+S Up-pipe today, when I fit this, will I notice a difference in sound on the standard headers (as I am running out of time to get the up-pipe modified b4 chrimbo!)
