Will Long-Tubes Pass Smog w/cats?
My smog is going to be coming up again in a couple of months and I'd hate to have to reinstall the stocks for just one test.
Also, would someone tell me what the purpose of O2 simulators are, and will a car pas smog with them? Do they make more power?
o2 sims are for when you remove the rear o2 sensors, its to trick the PCM into thinking they are still there. the other way to do that is getting them tuned out via edit or 'tuners.
