O2 sensor extenders
Has anyone used or can recommend an O2 sensor extender that prevents a check engine light when using a cat test pipe or hollowed cats. I see some have a mini-cat included so just looking if they work as i want to use on my C8 road racer. Thanks, Joe

I'd suggest their straight for a high-flow cat, or angled for catless. They also have a mini-cat version, but I have not personally tried that one.

Hopefully 🤞 the new tuning software will be able to delete these codes.

Spohn, thank you. I'll likely get these per your and Kracka's recommendation when I switch to the hollow cats. One of my cats blew out, chucks out of the exhaust 
so I finished it and will likely empty the left one.

Do you still have the mini cats- would you be interested in selling?
