Ok, I'm going to work on the NA performance after ditching my turbo project due to not enough cashflow (mortgage)...my car is
a 4T40E automatic so I think a 4-2-1 would be better then a 4-1 since I can't control the revs, SO WHAT HEADER SHOULD I GET AND 4-1 OR 4-2-1???
RK Sport 4-2-1 Header ?
Weapon-R 4-2-1 Header ?
Pacesetter 4-1 Header ?
RSM Racing 4-1 Header ?
Tsudo 4-2-1 header ?
Any others?
Don't buy from MANTAPART!!
RSM's is a pacesetter header, i think
I would go with pacesetter for more top end or RK Sport for more low end
Hope it helps

ECOTEC now with Maximum Bolt-Ons!!
I believe the RK Sport, Weapon R, and Tsudo headers are all basicly the same too aren't they ?
And if the RSM and Pace Setter are the same then you have 2 basic designs to choose from.
A 4-2-1 header offers more low and mid-range power where as a 4-1 header will give you more mid-range to top end power. It all depends on how you drive and what you want the car to do.
Semper Fi SAINT. May you rest in peace.
If you already have the turbo, manifold, DIS2, FMU, and BOV, why not keep going and finish the turbo project. Those are the more expensive parts if I'm not mistaken.
If you buy a header, then pay for the installation, that's good money you could put into your turbo kit. Plus, with a turbo, you can't use the header anyway.
i have the DC sports header and i love it.it pulls good all though the RPM range. what is with the stock manifold, the hole where it bolts to the down pipe is not open all the way its like a half cicrcal.

weapon r's is currently a copyof rk's , but there is word a new 1 is in the works
the pacesetter has been well used , and liked
