I am getting DC headers. one question. they have 4-2-1 headers and just 4-1 headers. whats the difference with them and which one is better?

 

the difference is that the 4-2-1 is 4 pipes leading to 2 pipes then forming into one. the 4-1 is 4 pipes forming into 1. If youve seen headers before you will understand what i am talking about. And then one you should get depends on the car you have.

 

DC sports doesn't make a 4-1 header for the f22 engine.

 

4-1 is for high end power, it will kill your power down low

4-2-1 is for broad power band.

 

Heres an oldschool pic of a 4-2-1. You can see at the bolts where 4 merges to 2.
