Multi cylinder misfires with fuel cutoff plus the o2 front sensor code p0153...p1341, p1357, p1355, yesterday it was p0306 now it's p1353 5-8 with coil pack and spark plug swap from L side to R side and I get the same results even after clearing codes. I should've gotten something correct by accident right?.... new intake gaskets and OEM OSV and no air leaks can be detected.

Could well be - remove the Lambda sensors (physically) and see if that makes a difference - also, a garage can measure the back-pressure at the sensor apertures - more info here:

If it turns out to be that cat, I'm screwed. I just moved to Cali. I've read about the smog emissions here are SUPER strict...

Don't sweat it, there are aftermarket cats that aren't too pricey that have worked just fine for members in the past with California emissions requirements. Worry about successfully diagnosing the issue first - we can help you get the right part once you work out exactly what you need
Well I've tried to break down the exhaust system to clear out the debris in the cats and noticed that from the manifold, it comes out as a whole and not in sections. The pipe won't come out because the rear is connected so, I can't get to manifold cat. I don't have the space (jack not strong enough to lift higher on to jack stands) to do it...nor do I have a pry bar long enough to break up the material even if I could get the rear cat off. If anyone has removed the exhaust, please chime in. I may be doing something wrong...
