Looking good. I have 4 sold so far. pending deposit.

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.
