No Cats Check Engine Light
I have a 03 GT with a O/R xpipe, american thunder flowmasters, 75mm throttle body and a CAI. My check engine light is on because i don't have cats so i was wondering what the best way was to shut off the light. I also have MIL eliminators but they obviously aren't doing the job. Any advice would be awesome. Thanks

You can make your own MIL Eliminators, from feedback I have received these have worked on 99.44% of new-edge Mustangs...

By cutting the O2 sensor signal and ground wires, and wiring in the MIL Eliminators as shown in this diagram (linked to on my "Make your own..." page)
Though many would gladly argue with me; the best way to make the connections is by using properly crimped butt connectors, filled with dielectric grease. This will beat the crap out of soldering which though not difficult does have a bit if "art" to it--also some O2 sensors use stainless steel wire which cannot be soft soldered--that's why Bosch specifies crimped connections for it's universal O2 sensors.
By properly crimped I mean using a die-compression crimper such as this one from Harbor Freight (often on sale for less than $10):
All other types of crimping tools are worthless, especially the ones from most hardware and home supply stores that just squash the connector into a flattened out mess.
Then tape over the butt connectors with electrical tape, or better yet use heat shrink tubing.
