Hi, I've got a 94 Integra ls and I was wondering if getting 4-2-1 headers makes a difference and if it's woth it? Also, are the ones they sell for like round 80-100 $ on e-bay as good as the DC sports one's?
If anyone could answer my question that would be great, thanks..

Oh yeah, and if I want them professionaly installed does anyone have any idea of how much that would run me about?

 

1. you have one header. :squint:
2. a header will make a difference, but usually not by itself. teamed with a free flowing cat convertor, exhaust, and an intake, it'll be more noticeable.
3. dont waste money on those cheapo headers

 

do it yourself. a few bolts and you're done.

 

You get what you pay for. So don't cheap out on performance stuff. h:

 

But if I put a header will it increase my gas consumption by much?

 

Your gas consumption will only increase from your lead foot, not from just the header. The cheap Ebay headers are complete crap. Yes you will notice a difference, coupled with other parts like snoopy said.

 

no it wont consume more gas or atleast a noticeable increase, i think maybe i got better mpg?

 

i <3 my greddy stainless 4-2-1 one piece header :thumbup:

i noticed a slight gain after installing my header. i also have an aem cai and apexi ws cat back. took about 45 mins to install it.

 

Most of the decrease in MPG will stem from the fact that your car will rev quicker and thus use more gas. If you drive lightly, then you will maintain your MPG or even increase it.

I've gotten up to 37 MPG (Freeway only) on my integra with AEM SRI, DC 4-2-1 header, RandomTech cat, and GReddy Evo with 5W30 oil and copper spark plugs.

And as long as you have no snapped manifold bolts, it's a quick and simple install
