Q:On this catalytic converter # 445009 will fit on my 2001 gmc Denali on the driver side as smog station says that’s the side that was illegal and needed replaced ? Show Less
Michael L.
A:BEST ANSWERHi Michael,
I'm glad to help you out.
This is not a direct replacement for the 2001 Denali. This is a universal fit converter that will require cutting and welding for installation. This should also match the EFN (Engine Family Number) VGM5.0HPG1EK of the vehicle that is found under your hood on the Vehicle Emissions Control Information (VECI) label. We still advise installing direct-fit catalytic converters on vehicles for better fitment and results on emission.
Here's a link on what we have available for the 2001 GMC Yukon Denali models:

I hope this helps. Happy shopping. Show less

P0430 Code: Catalyst System Efficiency Below Threshold (Bank 2)A failing catalytic converter breaks down less pollutants in the exhaust, resulting in lower oxygen (O2) levels overall. The downstream oxygen sensor detects the change and informs the vehicle’s computer. In turn, the computer activates the check engine light and logs the appropriate OBD-II trouble code for diagnosis by a
P0042 Code: HO2S Heater Control Circuit Bank 1 Sensor 3When there are only 3 O2 sensors it’s typically because there’s only one catalyst being monitored, and “Bank 1” is the default designation when there’s only one sensor in a category.
