I'm getting ready to order the magnaflow catted x. That is, if partshopper.com ever gets it back in stock for my car. I need to know 2 things: first, will i need O2 sensor extensions? And, would it be a good idea to go ahead and buy MIL eliminators, or will my engine light stay off?
I've had a Magnaflow Catted-X pipe for 5 years and have never thrown a code. Now that I have the Supercharger installed I turned off the rear O2 sensors (all they do is tell the computer if the cats are working) and installed a wideband O2 in the passenger side rear O2 bung.

The mustang shop that installed my magnaflow catted x-pipe told me 5 out of 10 cars will need MIL elims due to the check engine light coming on and the other 5 will still be ok with the increased air flow out the exhaust due to the high flow cats. Oh and I needed 02 sensor extensions.
1. You will not need extenders.
2. MagnaFlow is known for using hi perf cats that work well. They should not throw a code. I'd be surprised if they did.
3. I had my rear O2's turned off about a year after my Xpipe when I had a reflash done.
