I have no doubt that is how it works in some US states. Not where I live though. At 35 years old, the truck becam exempt from emissions requirements in 2023. I can remove the cat. Since there isn't a downstream O2 sensor it won't impact the ECU.
I do want to take it with me if I move somewhere someday. So thank you for pointing out that in CARB states you've got to follow the original design.
I have to say it's insane to think I couldn't put double the cats in it.
Toyotas with a 5.7 come with 2 tubes from the header to a "2 in 1 out" muffler. Each tube has 2 cats for a total of 4.
It's because the govt is r3ta@rded and can't make sane rules. Or maybe it's because they know D students are gonna be the ones to enforce them.
