hey all, i'm kicking around the idea of taking the cats off my bassani x pipe. had it on there for 4 years now and i kinda just want to change things up a bit. i have an SCT XCAL3 tuner with a custom RET tune installed. my question is, can i just go on there and turn the rear 02's on and off as i please and it doesn't affect the tune? like for instance, i don't want to turn off the 02's and the car resorts back to the stock tune or something. i would just like to turn them on/off as needed and not have it mess with the tune at all. is this as easy as i hope and i'm just overthinking this? thanks :thumbsup:
