Need Catalytics

Treachery · 08-14-2005, 10:59 PM

It looks like my luck has finally run out and i will have to remove my MAC H-Pipe and install (4) catalytic converters in order to pass the California smog check.

I know that there are threads about this subject but with California constantly changing the smog laws every year, i need recent info on how to pass. Registration is due in about 2 weeks.

What is best hi-flow kit out on the market that will pass the California smot test? I need the full 4 cat setup.

why dont you just stick the stock stuff on there for the check, then after switch back?? I live in minnesota so i dont really know too much about the smog stuff.

move to another state. just not illinois, tinted windows are going to be illegal soon.
but for now you cant have driver and passenger winders tinted.

well if knew they weren't goin to check you vin, i'd go find someone with a car exact that should pass emissions and give em 20 bucks to borrow it.

Yeah, it's a pain, i had to swap the stock pipe back for the test, then they made me find the stock airbox to put on as well, If you have MSD parts installed, you have to have the serial number and prove it's legal for use in Cali. I used the lowest octane, bought some smog pass crap and got through on my first try with TW heads, and a few other small mods. Good Luck.
