I need to reinstall my stock header/cat so I can register my car in CA. The problem is, I left it outside and it has some dirt inside the pipes from rain splash. I cleaned it out the best i could with simple green and paper towels, but of course there's still some dirt in there.

don't give me a hard time about my header getting dirty; it was stupid.

My question: does anybody think i'll have problems if I install it and run the car for a few days to get it smogged? I don't want flaming bits of dirt running through my exhaust system. To be clear, there's a very small amount of dirt in there. It's not visibly dirty or anything. I would just like to know if it need to be PERFECTLY clean.

Thanks for your help! I'll be gone for a little while taking off my race header, but then I'll check back here.

Exhaust gases will burn up whatever is left, you're fine.

unless by some act of nature some dirty finds its way inside of the head, then yes, you will be :thumbsup:

I would be most concerned with the o2 sensors since it doesn't take much to jack them up.

Hell, just run the car for a few minutes open header, that'll do the trick.
