Nice work, hopefully it will reduce some of "those" statements/questions. We Aussies are the worst - my Mrs shows me the AU Facebook posts (I do not deal with FB) where they're still talking about their pre- or post-GPF models. In Australia. This thread may be a little too advanced for them right now but they may end up here one day...

Just learned this a few weeks ago: If you open the rear muffler, you'll see that the rear muffler is bypassed if the flap is open.

Meaning, if you remove the OPF/mid muffler and the cat, you essentially have a straight pipe:p

Hi! I always have the same doubt, how can I know if my car is GPF or not?

The fastest way, go to your fuel door and see: If its round = Pre-GPF ; Square = GPF
So, I understand for this, if you have the latest version of the car, should be always GPF, correct? For example,if your car has been manufactured in August 19, sure is going to be the GPF...
