I'm on full "SS" (supersprint) from header to rear box, it's awesome, all sections are available, ST304 header, race cat, X pipe, 2 rear box model... definitely the best from my point of view.

you have milltek it look's appreciated around UK, but never tried and never seen one on my side,totally unknowed in my country.

I started by a "Gruppe M" titanium rear box but it's to noisy, take around a 100db at 4000rpm, junked it a few weeks later, I was kicked off all track days sessions

I tried Eisenmann rear box, not bad, good quality and dicression assured, only 85db at 4500rpm so no problems around.

with the full SS, extra power gain, slight increase on torque, and more velocity between 3300->7600prm.

I have a gruppe m rear box which is noisy as David mentioned, but that is what I wanted - lots of noise

! I had it put on after I did my track days.

See there's a Gruppe m on ebay at the moment plus a Supersprint back box....could be tempted with the Supersprint, anyone have any more comments on it. Is it a lighter exhaust than standard, as I understand the standard exhaust is pretty light as it is.

le Eisenmann rear box is slightly lighter than the original Csl rear box, and the road SS rear box is rather the same than the Eisenmann, and the SS race rear box is lighter than all others except the gruppe M

between a stock Csl exhaust and a E46 standard, there is 12kg (26.4lb) difference (cat+ centre pipe + rear box)

header I don't know

Where can you buy the Gruppe M from? Is it titanium?

The one on ebay is £350 used.

Yes, its titanium. I bought mine second hand from a guy on another forum. Be careful though as there are fakes out there. There was some guy on Ebay selling them brand new (he ws based in Canada) and they were fake. If in doubt, you can take photo's of the welds and send to Gruppe M and they will let you know if its real.

Andy, I am selling the one on ebay at £350.

I too was concerned about the possibility of it being a replica, but got in touch with Hoya, from Gruppe M in Japan and he confirmed that it was genuine and that the replicas were causing alot of bother in the early stages of fitment.

Mine has been on for 6 months now with no issues whatsoever, apart from the volume. As CSLGirl says, it is loud.

Just thought I would get my tuppence in, FYI I am interest in possibly Milltec these days, or maybe SS. We'll see.

Shame its just over noise limits as really it would have to be track friendly.
