Certainly understand your sophistry. In reality though your maybe has to be highly unlikely as compared to the other way around. Comprende?

sorry for the delay, the sports cup is the middle option. So it changes the rear muffler and removes the sides but no headers.
The car didnt have the exhaust on when it was at the dealer.




Also an update:
just got back my car a few days ago, it was at the dealer for a total of 108 days.
Took a while since its the first GT3 in Saudi that needed a topend, car seems fine but I havent done any high revs as I am waiting to pass 1000 KMs after the top end before high revving.
Will know the outcome in a few days
