hey ive got a 2000 civic si currently with these mods i have an apex n1 catback and an aem cai i am looking into purchasing a header i either want a jdm 4-1 or a dc jdm 4-1 can any one help me out by which is the better header and a nice price thanks in advance

 

common anyone?

 

The OEM 4-1 or DC JDM 4-1 should work well with your other mods.

 

dc jdm itr sits lower, doesnt have hangers for the skid plate, lighter, cost less...
jdm itr sits a little higher but is still low, has hanger for skid plate, heavier, cost more...
they both perform about the same...

I got the jdm 4-1, on mine.. i like it.

If your car is lowered, i suggest you get the same with a skid plate. Even though you are careful, i guarantee that you will scrape them somewhere somehow. My header have been saved by the skidplate twice, i hit 2 dips with it, all you see are scratches on the skidplate. gotta love it. Only bad thing is that their pricy.

The JDM DC 4-1, perform the same as you can see from the graphs on top. But the header is all staggered and hang low, and you will fuq them up if your car is lowered..lol good thing about them is that they weigh less and cost less.

Both are good. Just a buyers choice.

 

thanks for the help people
