I have stock ECU, hence I would like to replace my header with a light one that will not change the airflow, for as far as I know, if you change the airflow and you don't tune, the car will be slower.
I have AEM V2 Intake and
coming soon T1R 60R

So which header is almost like a stock but lighter ..the stock one is very heavy..

Well your first assumption is wrong, however...

The PLM or FF header are great straight bolt-on options that are manageable in price, however they won't pass CA smog visuals (No CARB #).

As far as I'm aware your CARB options are:

Comptech (I probably wouldn't suggest it without major supporting mods and tune, but can't really back that up)
DC (Which is lackluster at best)

You're probably better off just keeping the header stock tbh if your concerned with the legalities, if not, then read above. Oh I've also heard decent things about the T1R, but info is few and far between gernsby likes his though, but he's also tuned wickedly so

I will only answer to the question about which header is lighter and has the same design as the OEM. Its the DC Sports header.

If you added the stock heatshields to a light header then it becomes heavier, so whats the point? Go with the DC stainless one piece. It looks good, weighs less, has a CARB number,and doesn't cost much. You may gain a few HP too.

I'm not concerned with legalities So heat shield is not of my concern... I'm taking it to a auto cross ... NA engines allowed only, and I'm not going to tune my ECU... Any other options than DC headers ?

If you are not tuning get this header, its got the best gains and its made to bolt on and go without tuning.

kaissi

which one you mean? amuse or DC?

I have a JVT header and love it. One guy gained 4whp on a dyno just bolting it on, and its alot lighter than OEM so i'm happy with it. You can get a new one on ebay for less than $200. I havent had any problems with welds or anything and mine has like 10k miles on it. You honestly dont need a tune to put a header, but it will help get all the power out of it.

I have this header, I'm sure it's a replica of a good brand header... I have no idea though which one

All I want to know, does it look like it helps my car breath better and gain few HP.. at least not lose HP.. as I said I'm keeping stock ECU

The good thing about it is that it's much much lighter than the OEM header

I will put it with the T1R 60R
and my current AEM V2 Intake
