How much is too much? SMOG?
Just curious, at what point does it become difficult to pass smog?
I'm considering an LT1 Z28 but I'm in CA and I feel like if I my tire pressure were off by 1/2 a pound I won't pass.
Thanks

If it helps, my 93 in NJ (freakin way worse inspections than CA, I know cause I've lived in both) passed with a 1/2 gutted stock cat. The rear brick broke up, so I removed the remnants. Passed easily.

Sort of off topic but fastbird how do you like your headers. Those are the ones i'm gonna be getting. How did they affect the sound of the car. I also live in california. But unless you mess with the internals of you engine to much or go with no cats you should be okay. You will fail the visual easily but you can usually find a shop that will pass you as long as you pass the sniffer.

Well for instance if you relocate your cats you will fail the visual inspection but you will pass the acual emisions part. Same thing if you convert 2 cats to a single cat, you will pass the emissions part but not the visual.

I seriously haven't run into a single place this past year who performed a visual on my car
. Not that they don't but I'm just saying
The reason why I know this is cuz I took my car to several shops after puttin my cam in to do pretests to see if I could pass. Obviously it took several pretest attempts to pass the sniffer but after gettin a proper tune it was no problem--no one looked under my car.

My last Z28 with 355 w/ Vortech S-trim with 230/230 @ .480 lift on a 108 LSA passed smog. I just dropped in a 385 with same Blower and 228/236 511/533 112 LSA cam and hope to pass with that set-up. As long as your not running rich and your CAT is in good shape you will pass. By the way the blower helps with smog.
