There are many header options out there. Some of the best are:

Skunk 2 Mega Power Header

SSR Race Header

Hytech Header

ASP Header

DC Sports Race Header. Best bang for your buck. At least it is for me.....so far.

 

if you ever switch from the dc to the s2, its a night and day difference rico!

 

What's really interesting is how well the skunk2 has performed when stacked up against the custom exhausts. For those that haven't, take a good hard look at the quality of the Skunk2 header. It's easily the nicest mass produced header on the market IMO, then consider it's keeping up with the top custom exhausts. Just seems that Skunk2 has really stepped it up another notch.

 

Probably the Weapon R maybe!?! \:

 

That's a pretty steep claim. If I DO switch and you end up being wrong....I'll rip your f**king head off.

 

hahaha wow strong words lol
but yeah s2 it is unless someone else thinks different
what do u think josh?

 

My friend is using the S2 headers and he said they work good. But I'm also hearing from another friend of mine the Rcrew headers are good too.

 

one thing i dont want my check injen light to go on tho
is there any header that dont give out the check injen light?

 

Check Injen light? lulz...

 

You have to buy a defouler like the one Blox racing sells. The secondary O2 sensor screws right into it and the defouler screws into the secondary O2 port. That stops the CEL from coming on from race headers by tricking the ECU into thinking there is still a functioning catalytic converter.
