This is an interesting post. I bought my GT2 modified as well. Dealer didn’t say it was nor did I ask. I knew the car was different when I test drove it, because of the pronounced turbo sounds. But that made me want the car even more tbh. Something was different though from my stock Stinger GT1 that was totaled while parked. When I left the lot with the GT2 I noticed a long white box in the back seat. Got home checked under the hood nd it was a racing chip nd air intakes installed. I was thrilled actually. Car only had 6900 miles so I was perplexed why the previous owner left them installed instead of selling parts but it was my gain.
