Engine headers

The strength of the material and the grade of the steel determine the life of the header. Cheap metals or poor mixes will give you a short lasting header while better ones will give you longer life but you pay more.

is that header good then??
stainless steel is a better heat conductor is that a good thing??
open to other sugestions for headers

is this a 4 2 1 header ???

NO. The item description is all wrong. It's a 4:1 header. You can see it for yourself.

is dc sports a good brand??

can i trust them??
i really want mid range performance
i am in india and i ve know a guy with 4 2 1 header but they not really good i ve seen that guy working kinda messy and he dosnt do stainless steel
how are headers measured?
i ve seen dc sport headers on various sites most dont have a photo but describe it as a 4 2 1 header the pic in the previous poasts seems like a 4 1 right could it be a really 4 2 1???
or may be they ve just poasted the wrong pic

i mailed jp performance if they got a header for me this is what they replied cant make head nor tail of this experts pleasee help

4-2-1) can work great. They really work if the primaries are 25-30 inches in length If you try and do it in the stock space it is so short that it will still act like a manifold were the exhaust pulsation can go up and push the intake stroke out

and it ll be a custom header

They're saying that it's too short to make a 4:2.1 header for the corolla. I would stick to 4:1.

I wouldn't trust DC for Toyotas. They deal with mostly Honda/Acura. Big aftermarket companies are lazy and don't post relevant pictures up with the descriptions. It's most likely 4:1. They just used a generic description. I would go with a different brand that actually shows you what you are going to buy. What year do you drive?

03 corolla i am in a fix now cant seem to find a header ??
how are headers measured i think i ll have to get it custom made locally

The 4:1 header is for mid-top range power. I love the one I have. The 4:2.1 is good for low end.

i am getting really frustrated now
i am scared of getting a custom 4 2 1 now coz the guy from jp performance has scared me with all that intake stroke goin out thing

Don't get one custom made. Just buy one online. That will save you time and money and frustration.

no money is gonna be saved coz it ll be shipped to india u ve got a 4 1 header?

When looking for a header, you want to get an equilength tubing header so that it will reduce backpressure to help push more exhaust out faster.

but thats a 4 2 1 header
how much difference will i feel in mid range power with a 4 1 header??
