Wouldn't 3" exhaust be over kill for my application? 2 1/4" is just about right, 1 1/2" primary tube headers with the 2 1/4" exhaust system will scavenge the combustion chamber not only faster but more complete, doing this greatly reduces the chances of contaminating the fresh fuel mixture entering into the combustion chamber. I may have to use 1 5/8" primary tube headers. For the rpm range that my engine will be operating in I don't need big tube headers. Midlength headers may cost some low end torque from the research I've done and people that I've talked to. Is this correct or not?
