1999BlueTahoe

Good morning and thanks for the add. I just picked up a ‘99 Tahoe 4WD and of course it needs a few things. I’m quite certain it needs shocks and will be taking it to the shop to have the steering/suspension stuff checked out. It doesn’t clank or make any noises, just rides really soft.
The question I would like to address here is the P0420/430 codes. I have always been a Japanese car person and have never dealt with codes about catalytic converters. I am pretty certain that one of the previous owners did some exhaust work and deleted the cats. I think this because the truck is pretty loud but sounds good IMO. Is there any good reason to put cats back in and if so, what are my cat options? I can’t seem to find any universals online for the Tahoe and my local muffler shop wants about $250-300/per side. Also, do these trucks have codes that are specific to the o2 sensors? I would think there shouldn’t be any air/fuel mixture issues with the lack of cats if all the o2 sensors are working. Thank you.
