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?
 
there are fume issues from cheap aftermarket setups with poorly designed fume routing, which isn't the case with the stock system. If you want something that's a bit more noticeable than stock, but not too loud, consider the Welter Performance

Totally get wanting it quieter, and stock is way quieter, for sure. The fume issue? That's kinda hit or miss depending on the car model, if your rental was fine, yours might be too.

Going stock is easy and cheap for max quiet. If you want a little more growl but still chill, check out those 'touring' or 'resonated' aftermarket setups. It's always a trade off!
 
Absolutely, I can relate to that with my old '18. It came with an aftermarket exhaust that was really impressive in the beginning, but after a few months, the drone became exhausting during long trips. I ended up going back to the stock setup, and it was a whole lot quieter. I never ran into any fume problems myself, although I've heard those kinds of stories too. Like you mentioned, it really is a hit or miss situation. Eventually, I gave a resonated touring system a try, and honestly, it struck the perfect balance. If you're looking for a little extra sound without the hassle, it's definitely worth checking out.
 
Quitting a killer cat-back for stock is basically trading soul for safety compliance. Let's be honest, most stock issues are overblown; people just love complaining instead of enjoying a properly tuned exhaust.
