I do understand the dynamics of what you explained, thanks, but I have another concern, please.
What's the minimum diameter of header pipe and exhaust pipe can I use for a toyota 4af carb engine 1.6L 16valve 4cl engine?
From what you explained I guess that:
1. If I remove the CAT and Muffler, it will diminish the torque at the low rev range? Right?
2. If I use 4 separate pipes from the Exhaust Manifold going out as 4 separate exhaust pipes into one resonator pipe at the end, no muffler, no cat, would that be different in using a 4-1 aftermarket header going to a resonator, no muffler?
Emissions policy in my country is a joke, so I'm not after emissions and I'm not after fuel economy either. I just want to know HOW to make the most performance out of my old engine, that's all. I want torque to be readily available in the low rev range and max power at the high rev range. And I don't want any mufflers or catalytic converters, I want the engine to sound as it is.
Hope you understand.
