Im in Mesa, Maricopa County, Arizona. Looking to register and run my 1988 Monte Carlo soon. Stock set up with AIR pump, Cat, all stock emissions stuff. I passed emissions testing last year with all the stock stuff so I'm not worried about doing that again. My question is specifically for Arizona folks or those that are familiar with Arizona laws/practices. What aftermarket exhaust system are you using? I know way back when there was a header kit that included check valves and such for the stock system to tie into but those are long gone from what I've seen. The SS has an oval port "high flow, high performance" catalytic converter that sits off to the passengers side. Anyone running a kit that ties into this directly? Any other headers y'all recommend? What can be used on a SBC that will still pass emissions inspections. Im not opposed to swapping out the stock stuff and running it when needed for emissions but would like to set something up that's one and done. Looking for either headers all the way back or at minimum catback. I see some kits on Summit but would like some feedback from those that have a set up already and insight on what works and what doesn't.
Thanks in advanced.
