real quik 4:2:1
even though i never really felt the difference cause i always drive fast....
the real difference is......u should've searched this dude...its soo old....
4:2:1 is for street - more low end and mid range hp and torque
4:1 is for race - loses sum low end and mid range but gains more topend
if ur new to this...just
get dc sports 4:2:1 2 piece for ez installtion
and ur choice SS or cC

Not to tell you you're wrong.. but
What's funny is.. if you look on DC's site.. they have dyno graphs of a b16a and both headers..
the 4-1 didn't lose any low end power in comparison, but gained about 5 hp over the 4-2-1 in the top end.
Basically stating, both configurations have the same output on the low to mid. But the 4-1 adds more power up top. Check it out for yourself.
Although, I have always heard people say the same thing.. 4-1 loses low end, but those dyno charts prove that statement wrong.
