[Gruppe-S]

Hey all,

We just received the first prototype of our upcoming equal length header. This is obviously a prototype since the uppipe is a twinscroll design (that's for a different project we're working on). We're having the uppipe redone right now and it will be a 2 into 1 design similar to the one used on the APS header uppipe. Also like the APS and Perrin headers, this will require the 2.5L oil pan.

This header will cause you to lose your boxer rumble but it should feature better low to mid-range gains than our current un-equal length header. We will continue to sell the Gruppe-S V2 Header in addition to this new header. We will retail this header for $649 shipped and it will include the new uppipe. This thread has been posted to gauge interest in this header to see if people would be interested in a group buy. We would be looking for 10-15 interested persons and deposits would not be taken until we had at least that many. If and only if you are seriously interested (know for certain that you will buy one of these), please add your name to the list below. Feel free to contact us with any questions you might have.

Interested! More info on the Twin scroll turbo please!!!

[whitson01]

im for sure interested.. of course we would need some dynos to show the power it makes.. im glad you guys are coming out with one.. give some competition to the other makers

[whitson01]

also if you could post some more detailed pics including the inside welds that would be nice.. i know the perrin headers have had some pretty nasty welds on theirs.. just wondering what yours are like..
also what would be the GB price?/

These are the only pictures I have right now unfortunately. I'll post more as soon as we get more. The GB price will likely be $599 shipped.

Thanks,

they look beautiful. Would you be able to get them coated or would I have to send them somewhere after I received them? Also, correct me if I'm wrong, was it Perrin that was 4 into 1? And what do you see as the difference between 4 into 1 vs 2 into 1?
thanks,

i know as far as the honda/acura (non turbo of course) world, 4-1 will give you better top end power.. 4-2-1 is suspose to give you better low/mid ranger power.. so i dont know if that applies here too or not..

Hey Andy,

Thanks. We can have them coated for you. Coating would run an extra $200-250. The Perrin design is 4 into 1. Honestly, I don't think that one or the other is a better design unless you want to keep your stock uppipe. The only other thing I could think of is that the collecter is farther away from where the pulses originate. In this instance, I think this really has a negligible effect on flow though.

$599+$200 for coating would be a great group buy price

[iTSTi]

umm...$599, Good deal there. I wish I have to money right now. When is this GB going to close??

[lennyk1313]

It will start once there are at least 10 People. So I guess you are number 7?

[sti_my05]

I'm interested. 1 to the land down under.

Whichever header I decide to go with, I was planning on keeping the stock uppipe. Will these work with the stock uppipe? Would the power gains on these really be more noticeable with the uppipe on? Thanks a lot.
