  • Hint: Use a descriptive title for your new message
    If you're looking for help and want to draw people in who can assist you, use a descriptive subject title when posting your message. In other words, "I need help with my car" could be about anything and can easily be overlooked by people who can help. However, "I need help with my transmission" will draw interest from people who can help with a transmission specific issue. Be as descriptive as you can. Please also post in the appropriate forum. The "Lounge" is for introducing yourself. If you need help with your G70, please post in the G70 section - and so on... This message can be closed by clicking the X in the top right corner.

Has anyone done this yet and if so did u have to get some programmer or something after removal of the cat
 
If you leave your primary cats in place, you don't have to do anything. Secondary cats aren't monitored by the o2 sensors.
 
I’m thinking about putting a cutoff valve before the resonator and leaving everything stock.

I know that a cuttoff can be installed before the muffler but does anyone have any experience doing it before the res?
