Bone stock vs CAI, our tri-y race header (first design), 2.5" H.A. exhaust and a full tune

The concentration point here is the mid-range. Our 4-1 and our tri-y both made similar peak power, but good peak power that is



Mods on the car
Injen CAI
H.A. Prototype Tri-y race header
H.A. 2.5" Cat-back Exhaust
50 lb tire/wheel setup (cost a few hp)

Mikey, please plot your two headers for comparison on the same chart. Looks great! Again, look at the area under the curve!

ya, I was running into problems with the dynojet printer, so I rushed this one to my email and got it here at home.

From what I remember, the 4-2-1 has a much beefier mid-range up till 7k where it meets up with the 4-1 for the top end.

Tomorrow is our first ever dyno day, but I'll try to get that comparison for you
