stupid header question

Grey2.0SI · 06-05-2008, 01:37 AM

im lookin into the DCRH and keeping the rest of my stock exhaust. When i remove the current exhaust manifold for the DCRH, will i still have my stock cat? If not, can i just buy a HFC and bolt that on with the header? i just dont want to have to mod my o2 sensor unless i have to, and i still want to pass emissions...

thanks!
Michael

the Race Header eliminates the cat

so i'll need to do the O2 mod? will that pass emissions? Guess ill just have to get the vibrant with the cat installed :/

go with the vibrant man.

the header should have the bung for the defowler.

U wont pass smog without a cat anywhere, unless u do it illegally.

But!!!, u shouldnt have to smog ur car for a while, so my suggestion would be do it, and worry about smog when that time comes. I know here in Cali, we have 6 years til we have to smog a new car.

well, my dad is a stickler not to cheat and lie so im guessin he'll flip shit if i have to mod my exhaust to hopefully pass so i'll stick to the vibrant. reliable, legal, and still more performance

Technically the vibrant HFC is illegal, but you might pass emissions.

i thought our cars run clean enough to pass emissions without a cat ?

LMFAO! The cat is the only thing that basically does the job! Get rid of that and you got instant performance!

i dont have any personal experience with this yet but some will tell you that it is not recommended to run a header with the stock exhaust. This is why i am waiting to get an exhaust to put my header on...
