1. Why is the exhaust in his setup too large?
2. How could it not help the setup's power? ......provided he correctly tunes for it, which is 100% doable. BTSTDT, have you?
3. If the exhaust is too large, why does a properly tuned setup with C3/C4/C5/E7/GT40/GT40p heads perform better, with open headers? BTSTDT, have you?
4. So it makes sense to spend $$ in choking the exhaust, rather than utilize/capitalize its better exhalation cycle capabilities and spend that $$ on the intake instead? Why not match the inhalation cycle in the engine? Wouldn't a better breathing engine setup make more average power?
5. ...5.13:1 gears compare to a 3" ID full exhaust?.....

Would that be too much "techno babble BS" to answer?.... for the benefit of the OP and the membership?
