2014 GMC Yukon XL 1500 Catalytic Converters

When you need them

A P0420 code, rattling from underneath, or a failed emissions test. On a full-size SUV, suspension type and towing package split this group, and neither is visible from outside the vehicle.

Why buy OEM here

• Wholesale pricing. Most catalytic converters numbers land well below dealer list.
• No aftermarket substitutes. These are GM catalytic converters, not OE-style equivalents.
• We catch the wrong part before you do. VIN verification is free on every catalytic converters order.

Getting the right part

OEM components carry GM warranty coverage, which is usually worth more than the price gap on the invoice. If you are unsure which version you have, give us the VIN and our specialists will confirm fitment. Stock moves out the door the day you order it, assuming you beat the mid-afternoon cutoff.
