I used the search function for headers and most of you have GSR motors with 4-1. Now for the LS motor, which would be a good choice having a redline at 6800rpm? DC JDM 4-1 or DC CC 4-2-1?

 

use the 4-2-1 cause it will give you more power throughout the low end and mid power range

the 4-1's are better for gsr's cause they redline at 8, so the 4-1's help better in the high end

no point in gettin' a product to increase your high end when you can only go to 6800rpms, so go with the 4-2-1's

 

if u do get the 4-1 dont dump ur car more than 1.5 inches... otherwise say bye bye to ur header once they start to do road construction again... bastards
