    Default 09 silverado catalytic converter removal

    On my 09 silverado there are 3 catalytic converters the 2 on the manifolds have o2 sensors but the one in the exhaust pipe has no monitoring at all. Is it worth removing the 3rd one for less restriction or is it not worth it? Also will it throw a code some how?
