Got this 2020 S that came with a Thermal R&D Cat Back ceramic coated dual exhaust from the previous owner. It sounds great actually, but honestly, I prefer something a bit more quieter and im thinking about going back to stock tho Ive heard the stock setup might have some issues with exhaust fumes. The one I rented before buying this car didnt really seem to have that issue, but I'd love to hear from anyone who's running the stock exhaust or has the same setup, how do you like it?
