Which Gives More TORQUE POWER...

Which Gives More TORQUE POWER a 4-2-1 (2 piece), 4-2-1 (1 piece) or a 4-1 (1 piece).... Stainless or Ceramic(w/ HEAT WRAPPED)???? and Which is better off if you were sitting on the pole position, which HEADER gives you more POWER???

The design plays a diference in where you want your powerband to be located. 4-2-1 headers are designed to make low to midrange power. 4-1 makes high-end power with the compromise of low-end torque/hp. 4-2-1 headers have very good ground clearance, compared to that of the 4-1 because the collector sits very low.

blue-4-1
red-4-2-1

you can see where the power starts on each of the haders, its very simple to see what each design was engineered to do.

Ceramic is cheaper than stainless, its designed to reduce heat from the headers. But from my experience with ceramic headers, they have the chance of cracking if you happen to bottom out.

Go with the stainless, its pricey but you get what you pay for.
