Gruppe-S Engineering

Hey all,

We've also got our own header that works great for your EJ205. Quality is very high and fitment is good. For the price, it can't be touched. Our manifold features T304 Stainless Steel piping, mandrel bends, and CNC precision cut flanges. The 4-1 collector is cast to ensure the smoothest possible low rates. Strong gains in both HP and torque can be expected with the addition of the manifold (yes it will actually make power!!!), especially with high horsepower applications. Includes all necessary gaskets.




$450 USD shipped.



V2 Manifold + Helix Flex Uppipe:





$600 USD shipped.



We would like to get at least 5 buyers for this price. If interested, please PM or email.




Thanks,

Max

Any particular reason no one is interested in these? Questions? Concerns? Would dyno charts help?

Thanks,

Import duty and taxes on top of the initial outlay maybe.
Still a great price though TBH.

Prices with up-pipe too would help... presuming that price doesn't include one

Some people have concerns about cracking/splitting etc. Also should or shouldn't these be heat wrapped?

Gruppe-S Engineering

Hey all,

Thanks for the input. It will help us get you guys what you want.

Understood. Thanks! For the quality and fitment of the header, that price is amazing.

We have sold hundreds of these headers in the US and only one has cracked because it was Jethot coated. We stand behind our products and would be more than willing to replace any product that you buy from us if it was defective. Our extensive dyno testing has shown that these headers will benefit from being wrapped.

We could do our header with the Helix uppipe for 360 GBP shipped. Quality and fitment are very good on this unit too but it's currently out of stock. We expect to have more in about 2 weeks. Here's a pic of the uppipe:



If you have any more questions, please do not hesistate to PM or post.

Thanks!

Can these be fitted unwrapped without causing any problems to the engine/turbo etc.?

Gruppe-S Engineering

Yes, they can.

Thanks,

Will i loose my scooby burble if i buy these>?

RON

No you won't, these are 'UN' equal length.....

tath

so after import duty etc how much will i be paying?

Stiver3

Thanks, but im guessing these dont give as good results as equal length headers?

tath

yeah if you're running 500bhp then you'll lose out on a couple of bhp... the sound outweighs the marginal differences in power IMO

Interested in duty price also.
...Or, could it be sent as a 'gift'

Stiver3

Cheers mate

scoobynutt

hi all iv done a bit of searching on what the duty on these should be and its 2.7% then plus vat 17.5% witch i think comes out at £301 all in this is based on the info iv found so i stand to be corrected if im wrong

matt

Gruppe-S Engineering

Stiver3 - The manifolds are non-equal length, so the boxer sound is retained

fiestaboy - The customs value is the insuraed value.. that's all we can say. We haven't had any lost/damaged packages yet though

Thanks,

Geoff

RB5Caterham

I might be interested in this but with the flexi up-pipe.

beanybens

Am i right in thinking these headers fit the classic 98/99 sti???
Thanks Matt

RB5Caterham

Yes. They will fit the Classic shape scoob I believe.

beanybens

If they do put me down for a set with the flexi helix up-pipe

Cheers Matt

Brother_Will

Shame you dont do anything for the 2.5RS

beanybens

Any news on stock yet gruppe-s???(including helix flexi up-pipe)
Matt

Gruppe-S Engineering

Helix Flex uppipes are back in stock now! :-D

beanybens - They do in fact fit the GC8 chassis Impreza's with no issues

new boy - Yes the manifold will fit with a Gruppe-S uppipe

Brother_Will - Was there anything specific you were looking for?


Thanks

Max

SCOOBYD00

Anyone got one of these fitted - 100% you do not loose the scooby flat 4 burble. ?
Can you describe how the note changes with these headers?

RB5Caterham

Normally with any manifold upgrade, be it equal or unequal length, you dont loose the Scooby burble which really happens at lower revs, upper revs you do but then it sounds like a super bike.

Max, how much shipped to the UK with the flexi up-pipe? Anyone know how much import and vat we're likely to pay?

beanybens

I am awaiting contact from gruppe-s to arrange payment for the headers and helix flexi up-pipe....Looking forward to getting them on my car
Regarding wrapping the exhaust,is it just the headers that should be wrapped?Where do u buy the wrap from?
Cheers in advance Matt
