Thinking about stainless works catback
I have a A8 NON dual mode exhaust. I'm thinking about getting a stainless works cat back exhaust and was wondering if I get the kit without the AFM valves, I know it has a spot where the AFM hooks up but there isn't the valve on the inside, but will it throw any sort of code? Any advantages/disadvantages getting rid or keeping AFM?
I'm wanting to do the exhaust without throwing any codes.

No code will get thrown for the valve delete, but a code will get thrown without the 2ndary cats. The SW system does remove those 2ndary cats that follow the 02 sensors. They advertise the system as a 'Off Road' system. So to avoid CEL's you may need a tune.

From what I've read, those that have gotten a CEL after secondary cat deletion, they've discovered bad welds which caused a leak in the system. Those that have had proper welds when installing off road pipes in place of the 2ndary cats have had no problems with codes.

I installed SW's full system(off road, no cat's) last week and i do not have any CE lights. I've put about 50 miles on it so far with zero issues besides all the neck injuries from people looking to see what the heck is coming down the road! I haven't had it tuned yet either but will be doing so soon.
The afm valves are simply for to get better mpg's. Personally i didn't like it going in and out of V4 mode so that was the first thing i bypassed. I didn't buy the car for the mpg's anyway. you won't get quit as good mpg's by deleting it but to me it was worth it as its a V8 and that is how i want it to act all the time.

Do you have aftermarket headers?

No, it would still kick the car in v4 mode you just wouldn't have the afm valves opening and closing. Not sure if that hurts anything or not regarding exhaust back pressure over the long term. I thought I read somewhere that it's okay to have it like this. I would just buy the afm range disabler and be done with it. It's only $100 or so and then you don't have to worry about it. That's the route I went.

Works great! Yes, you simply plug it into the obd port when the car is off and that's it. Your left with the V8 car you were wanting in the first place!

This is a good question/point. If you have the SW headers you WILL throw a code. You will need a tune to get rid of it and you should get a tune to take full advantage of what you're adding to the system. If you did the cat back exhaust or axle back exhaust you shouldn't be throwing a code and you don't need a tune. If you are throwing a code, that indicates a bad weld and you have a leak in your system.
