Front cats

Will the engine light come up if I remove the front cats from my 03 gt?

As long as you have a pair of cats upstream of the rear o2 sensors you will be fine. Aftermarket catted pipes all have 2 cats and they are just fine. The 6 cats on the stock pipe is beyond overkill.
2000 Mustang GT Steeda build #48. Bolt ons, suspension, Novi 2000.

Just because I give you advice, doesn't mean I know more than you. Its just means I've done more stupid ****.
