Seen alot of posts like this but none that quite answer my question. I have a 2018 Sierra 1500 Denali with the 6.2. I am thinking about installing an electric exhaust cut out before the muffler. (For arguments sake let's say my best friend is the warranty manager at my local dealership so I am not concerned about warranty mumbo) What I'd like to know is if I am going to run into any check engine light or any other messages popping up that she will pissed at me about it. I noticed alot of people with '14s and '15s not having issues with them but I feel like this 2018 has so many sensors and is so touchy that I'm hoping to hear from someone on here with the same year that has done it or knows of someone who has? I dont have any oxygen sensors back that far but is this engine computer smart enough to realize there is no backpressure from the muffler or something like that. I may just be being paranoid but really dont want to have to look at an idiot light over it. Wouldn't be worth it..or would it Any logical input would be very appreciated!
