I made 4-1 TRD copy from mild steel.
Yes, 4-2-1 is better for smooth torque curve but 4-1 gives more power - in narrower range. I built 4-1 with long primaries - to avoid power peak at very high RPM so the header is usefull to gain power even in 6000 RPM range (will test it on dyno and see exactly what's going on). I can fabricate 4-2-1 if you prefer (it's even easier becouse it doesn't need 4-1 merge collector). |
