Tri-Y Headers for torque?

Yes, and now that you say it I remember reading here that DD put the front-rear "Y" back near the rear axle and it gave good off idle power.. that is what I am looking for.. Then how to size it so it does not become a cork at 4500.. but realistically I am in the 1500-3000 range and most often 1800-2800..
But generally at part throttle, unless your pushing the throttle over 1/2 - full to do normal driving around town your already making more idle-3000 rpm power then you use.
i will go look up the speed talk topic and see what I discover. Thanks!
