As much as I hate to admit it, and I can understand 100% why not to go with knockoff as it hurts the industry and all...but in the end of the day the Isis/Godspeed/Ebay 'Freddy' manifolds make the same power and torque that the Greddy does. Don't get me wrong the casting isn't as 'nice looking' and you gotta/should retap the NPT fitting holes...but aside from that, for the 200-300 less dollar price...it's *every* bit as good.

3. You lost a LOT of top end. I mean after about 6000 RPM, your torque and HP drops like a rock.....
This is what I found....

Exactly my point. Forever peole used to talk about the midrange 'supremacy' of the stock manifold down low....reality is, who really cares about 10 ft lbs on a dyno from 3000-4000 rpm when you can gain 15+ hp and trq average?
