Think they will say anything?
I live in Colorado and have life time oil changes through the dealership and some extended warranty left. I recently had a cat delete fabed up that i can take on and off. I only have to get the emissions checked every 2 years. So my question is, should i worry about switching the cat delete out when i take it in for an oil change? I have only had 1 oil change done by them since i bought the truck and don't know them too will yet. I would hope the tech wouldn't say $h** about it, but i'm not sure. Any opinions?
