2014 Cadillac CTS Catalytic Converters

Genuine GM catalytic converters for the 2014 Cadillac CTS, at wholesale prices. Converters are emissions parts, and the substrate loading has to match what the ECM expects from the downstream oxygen sensor. Second generation Sigma through 2013 and the Alpha based third generation from 2014 to 2019.

Symptoms to look for

A P0420 code, rattling from underneath, or a failed emissions test. On a mid-size car, trim and package content split these part numbers in ways a diagram will not show.

Buying OEM, briefly

• Factory warranty. Genuine catalytic converters carry GM coverage aftermarket cannot match.
• Dealer parts, not dealer prices. Compare our catalytic converters pricing against a counter quote.
• Genuine GM only. Every catalytic converters listing carries the original factory part number.
• Fitment checked by a person. Send the VIN and we verify the catalytic converters before the box leaves.
• Central shipping origin. Dallas keeps catalytic converters transit times short nationwide.

Ordering correctly

Factory parts are built to the tolerances the vehicle was engineered around, not copied from a worn sample. A photo is rarely enough to order from. The VIN takes seconds and removes the guesswork. Freight is quoted at what it actually costs, not inflated to subsidize a headline discount.
