I wonder if we could get a dino of all the Kooks headers for comparison to each other, but then again we aint all independently wealthy. :lol1:
So the general consensus for a supercharged application running E85 all the time is Kooks 1 3/4ths?
i would not put the 1 3/4 on a power adder car, for a normal s/c car, i'd run 1 7/8, for a 1000 wheel, 2", we run a 2, to 2 1/8 to 2 1/4 stepped
but we only run 7.7s so what do we know about making power
Aren't headers supposed to be stepped down as the leave the head, not stepped up? The gas cools as contracts as it leaves the head. Smaller diameter maintains velocity despite cooling. Going up will just expand, cool and slow gas and potentially stall it.i would not put the 1 3/4 on a power adder car, for a normal s/c car, i'd run 1 7/8, for a 1000 wheel, 2", we run a 2, to 2 1/8 to 2 1/4 stepped

Making the switch from BBK 1-3/4" to Kooks 1-7/8" headers soon. I had the BBK's installed before i decided to go FI so should be interesting to see if I gain anything.
