Hello Everyone,
Message board member ThunderDump posted a message about the exhaust muffler valves for the 2021-2024 models, which are now controlled via Electronic Exhaust Valves. He is correct.
SuperSprint is currently in the process of developing a new exhaust muffler, specifically for the newer cars that have the Electronic Exhaust Valves. Right now we are in the R & D stage for development of the new F Type R exhaust system.
The expected release date is September 2023. Once the new exhaust muffler is released, we will let everyone know its available.
Thank you....

Respectfully,
Roberto
