Hey guys, I'm looking into gettin my race header (finally) and was wondering what would be better for acceleration, i.e. quarter mile times and such. So would a 4 into 1 header or a 4 into 2 into 1 be better? Thanx

I believe a 4-2-1 give better overall gains then a 4-1. I have the FC 4-2-1 Race Header and I love it. So much better acceleration with it.

nobody knows for sure which one is better...there is speculatoin...and personal preferences to one company or another... it is beleived that the 4-1 design will not benefit a lower hp motor as much as the 4-2-1 design...but that if u plan on being a very high na engine or even jrsc..that the 4-1 could benefit your cause more...like i said tho...nobody has dyno tested either of them on the exact same car with exact same mods...go for what u want and enjoy
