Headers vs. Manifolds

It's the old air-pump logic.
You spend a ton of money changing a 3 inch pump into 4 inch,
- a ton more money changing the heads, intake, carb, camshaft to change the 3 inch inlet to 4 inch, and you leave a 3 inch outlet on it.
Totally backward try to cram all that flow thru puny exhaust system, and then no tuned or scavenging exhaust .
Do it the other way, exhaust first,
Or just bullshit and say it's anything, who's gonna know or care, but the very first guy and everyone else that sees manifolds isn't likely to believe the rest.
Decals are cheap.
