whats the difference between a 4-1 and a 4-2-1?

 

no one knows?

 

4-2-1 will give you better lower end torque and midrange power.. while the 4-1 will give you more high end power... now which one will be better for you depends on your set-up and goals..

 

interesting... any idea how much these differences might amount to? i hate to be the douche to ask for numbers, but just to get an idea if its worth it to go one way or the other over the subject.

 

Go with the 4-1 if you want to notice any kind of a difference.

 

that'll work for me. thanks man

 

I just finished installing a dc sports 4-1 header to replace my cracked oem manifold. I can definately hear and feel the difference in how the motor flows. I don't have any other mods to go with the header, nonetheless my motor feels smoother than before. I think that the gaping wound in my oem manifold was creating turbulence and hindering exhuast flow while being annoying loud. Eitherway i'm pleased that my teg no longer sounds like a chevette and has smoother output. As far as hp #'s go I couldn't begin to say, but it feels better.

 

I agree. I once installed a dc 4-2-1 and did not notice jack shit of a difference. Then I installed a kamikaze 4-1 and felt a world of difference. At least 100hp. J/K about 4.

 

get a hybrid 4-2-1 and get the best of both worlds. although more expensive than traditional 4-2-1's and 4-1's
