Fact or Fiction ???
You have a stock car with a given air intake velocity and given exhaust backpressure.
*If you increase the intake velocity over stock and leave the exhaust the same(stock), you will create more back pressure, hence a drop in hp and torque.
*If you have stock air intake and new exhaust with less backpressure, you may lose some low end torque but gain some high end hp.
*NOW, if you increase air flow AND reduce backpressure by use of non stock intake box/filter and free-flow exhaust, would'nt it follow that you would have more hp and torque over the same rpm range as the original intake/exhaust setup???

Looking for techinically astute replies based on experience and not old myth's. Thanks...
Bottom line, I am interested in BOTH reducing backpressure and increasing intake air flow with the objective of gaining more hp and torque over the same rpm range I have with the stock setup....
