Some interesting info I can share and I heard it earlier. I asked this old mechanic how can I tell if the cats are going bad. He said there are two ways to find out. Once the car is fully at hot temp, check the cats if they’re cherry red and do it at night. If it’s red, of course it’s going bad. The other is usually going to throw the engine light and the car will die if the cats are clogged up.
I wonder if these tuners turn that cat signal or sensor off before throwing that check engine light to prevent more damage to the engine?
