Thanks, in my early stages here your step up is what i am leaning towards. In part due to sound, but in part due to cost. The headers (kooks or otherwise it seems) are pretty expensive, given the anticipated gain. E85 is in my plans as well. the plan at this point is addressing the intake system up to heads (including head porting if i can talk myself out of the $$), exhaust system, and fuel type.
Curious, any idea what hp you picked up with the kooks and green cats? (or was it with the E85 at same time)
