3. There is a difference between 4-2-1 and 4-1 in performance (not sure exactly which is better tho)
4. Bigger pipes are not always a good thing!! DC header has torque gains throughout powerband and HP header has more high end power. The difference?? HP has bigger piping and DC has smaller piping. Having some preassure in there helps preserve torque, where HP's higher end only comes from having bigger pipes to move more flow non restrictivly at high speed, but looses that low end torque as a result....
Does any one have ACTUAL info on what gains are to be had with the borla header and where those gains are (HP?, Torque?, High End?, Low End?)

Couple of points.
