We will have headers made for them by Ultimate Headers. these are really tight and will be 321 with slip fit collectors.
keep in mind that at this time the LS is the ONLY combination we are working on. I am pretty confidant in saying that a BB will not fit this sub frame. but then again if you want a BB you would probably be more than happy with our current ProTouring subframe.

I would not do slip fit collectors on an LS engine, the o2 sensors will not read correctly.

Thanks Dave, We actually have the O2 bung mounted in the slip. so that it is about 6-8" from the merge point of the tubes. Then we suggest using a 3" wide band clamp. This also allows for the o2 to be rotated to the position you want and give a good starting point for the exhaust to be started.
but I agree most of the time it would be mounted to far up stream in the collector. We have addressed that. So many things to consider!!

Looks really good fellas! Congrats on bringing a new option to the market.

[Ben@SpeedTech]

Thanks for the compliments everyone!

As serious as autocross and road racing are becoming, the whole purpose of this subframe is to take the "Pro Touring/ G Machine" world to the next performance level. Quite often that means the guys with the deepest wallets are the only ones that get to play (and hit the top 10 at events). We say that time is over, it's time to level the playing field.

The ExtReme subframes have an AWESOME introductory price of only $6899, plus crate and shipping. This isn't a stripped down base model version that you have to upgrade for it to reach it's potential, this comes with all ultra high clearance suspension components, Viking's new Crusader double adjustable autocross valved shocks with your choice of spring rates, splined sway bar with several rate options available, Sweet performance rack and pinion, LS engine frame stands and fully adjustable transmission cross member. The package ALSO includes the new exclusive ATS ExtReme spindle, which has better geometry numbers than any Corvette, Vette copy, or any other spindle out there. Pretty much you just add the brake system of your choice, body mounts, and a steering shaft, all of which we can set you up with. The frame comes bare for painting to your needs, or we also offer an optional powder coating service.

We've seen some great success from Viking's Crusader shocks, they have some very aggressive dyno figures and from a real world point of view several of our customers use them, I have them on my car and we have them on our C10 (Click Here to see build photos). They perform fantastic on the street and incredibly well on the track! We don't want to leave anyone out however, so to make sure we cover everyone's needs and wants, we also have JRI and Ridetech on board for shock options.

All sales hoopla aside, with the experience of Speedtech and Ron Sutton paired up to perfect the design, the serious handling potential of this set up, and the fantastic price, is there really a need to shop further than the Speedtech ExtReme subframe?
