Passing smog with header

STG3M3 · Tue, Aug-24-2010, 09:14:25 PM

Hi everyone I have just ordered some e-bay headers and I was wondering if there is a way I can pass smog in Cali with the headers without putting the stock ones back. The rest of the system is stock for now I am getting a Gruppe-M muffler from one of the members here. I was thinking about buying Agency power rasp term. with maybe getting a custom sec 2 with AR20's welded on. Or something like that, what can I do to pass smog and not have rasp???????

Thank you all I will post some pics of the car as soon as I get everything installed. Photo-shoot coming soon.

you will HAVE to get cats or else you won't pass the sniffer. even with my euro cats i BARELY made the cut for HC output and nearly failed. i'm in cali as well, so trust me.

Well I am running the euro cats. I paid 750.00 for them...

euro cats or custom performance's cats seem to be reasonably priced. there aren't too many options out there unless you go custom which is a pain, you will have to get O2 bungs welded into the correction places and etc etc..
