98 lude and im thinkin bout gettin some race headers, which one should i get 4-2-1 or 4-1 and can you guys list the power gains and where they would take effect(low end, mid range, or up top) thnx!

 

4-1 = more of a top end header
4-2-1 = more midrange power

i went custom....

4-1 header-tech header stepped with a 3" collector with a 3" exhaust...works great for me..

 

thnx for da fast answer, yea im lookin 4 mid range b/c i got my v-tec up top and i need the most power i can get in da low end and mid!

 

then go with a 4-2-1 design, or you can still go custom with one of the better manufacures.

The collector size in theory should be smaller than the exhaust size.

So When doing the DC collector mod I should use a 2in collector instead of a 2.5 in like the rest of my exhaust.( isnt the collector around 2 in. )

 

in reality, the same size exhaust will work....

Ya But Have'n a 4,1 on a Vtec engine is going to help VTec out more right?
And Concidering that you make your Peak horses at About 6800 wouldnt the
4,1 give you the chance to make even more power During Vtec?
