even with no cats and straight 2.25" piping? i wonder if i can shorten my runners on my header? make it collect sooner? does it make that much of a difference; even so, i'm not gonna buy another header cause soon i'll have an exhaust manifold with a turbo slapped on it thanks for the insight guys! oh yea, CARL; how much of a difference does the timing make on your power band???

 

Yea its interesting how different it feels with different length/dia primaries.

Timing (if its at optimum) doesnt affect powerband in my experience.
