few questions,i have a 4-2-1 header and was wondering if i could benefit from usins the 4-1 header? they are both dc sports carb legal. Or any other header that would help the cause!

 

4-2-1 will give you better low/midrange, 4-1 will give you better top end. Use a search, billions of topics about this.

 

Yea mani did the search and it works. I was just wondering if you could trade straight across would it be worth it? 4-2-1 for 4-1

 

theres no point if you already purchased the dc 4-2-1 in trying to sell that one and buy a 4-1. the 4-1 might get a you 1-2 hp more than the other but its truly not worth it. and if you are going for some crazy all motor set up or supercharging it then dc isnt the header to have anyway.

lo/midrange is o-around 4500 rpm's mid/high is 4000-redline

 

civic till death you have given me alot of info since i have been here thanx man! You think i should go with the 4-1 instead?

 

it depends on how you drive your car.

me= always above 4000 rpm's so if i get a header it will be a 4-1 simply because a 4-2-1 will slow my roll.

if you drive at lower rpm's id stay with the 4-2-1

but if you plan to go turbo, i would keep what you got

its all in the foot of the driver

 

thanx man one final question. will the 4-1 off a 99 b-16a fit on a 2000 b16a2?

 

yes, b series are interchangeable with each other

 

Did the b-16a2 make more power than the b16a?

What is the best way to get keep header bolts from stripping?

 

anti-seize compound on the threads before you install the header. then torque them down with a torque wrench to 23lbs (i think that's factory spec.). becareful not to over tighten cuz if you break a stud, you're screwed. good luck bro!
