Purchase 2021 Tundra TRD Pro question

In the process of evaluating a 2021 Tundra TRD Pro with 73K miles for purchase. Showed up at the dealer to be surprised and unprepared for the build of the car as I wasn't told about these details. I'm not a car expert by any means but the vehicle has significant mods that I didn't know how to evaluate properly.
Harrop supercharger, custom exhaust with mid pipes I believe, custom lift/suspension among the obvious findings.
I scanned it and found P013A, P013C confirmed trouble codes, P0139 permanent trouble code
The dealer handed me the inspection report and the result was "passed." The O2 sensor showed "ready" status, evap "not ready", heated cat "not supported", air cond "not supported". Everything else was "ready" on the status of sensors on the report.
Is this possible or did they do something for the truck to pass inspection?
Any input is greatly appreciated and whether walking away is the best thing to do since I don't really know what I'm getting into problem wise with the mods.
Thank you, Cezar

 

You answered your own question

 

Sounds like they stole my truck and selling it there. JK

Those codes are from most likely having long tube headers and no cats or high flow cats. They can be corrected in several ways and don’t impact the actual vehicle. I used to get them frequently in the same application and got rid of then with “mini cats” but you can also remove with tuning.


That truck is likely hilarious to drive. It is concerning someone traded it in, but maybe was a fun toy and moved on.

 

I recently bought a CPO 2021 Crewmax. In my case the dealer's idea of an inspection was to detail the truck and put it on the lot. Maybe there are no big problems, but why did they not fix the problems before they put it on the lot? If you think you should walk away, walk away.

 

Should probably take a closer look at the emissions system, especially if your state has yearly inspections. Dealer is probably on the don’t ask, dont tell package. I’d assume anything with a supercharger to have a modified exhaust system. Could be a major score as they will likely lose sending it to auction. Could also be a money pit.

 

How much is that 2021 Tundra TRD Pro with 73K ?
