My son has a 2000 Mustang GT. He wants to take off the cats and straight pipe it from the exhaust manifolds to the mufflers. Can they put bung holes in the straight pipes for the 4 O2 sensors? Will they trip the check engine light with the 4 cats removed? Solutions?

Is there a Mustang expert in Nashville I can reach out to?
