looked remarkably similar to my HP Performance kit... 
Also, was this 600hp pull on the RC750s or the 1000cc injectors?

hmmm, i wonder if you know something other people don't... 

The only real apparent difference (from what I can see) is the 2.5"DP compared to my 3"... but the header may also flow completely differently... this is based on that YouTube video only.
I just hope its decently efficient. This same kit made 353rwhp @ 13psi on stock compression for HP's car (went 12.2 in the 1/4). Imagine what that would be with a Mase Engineering tune... w00t!John
its prob slightly different to ur hp manifold due to the rhd issuse with my car, hence it having to be custom made, however most manifolds do have some similar designs, have u a photo of the manifold and i will tell you if its different,
