My brother has a newer Vette and mentioned that you can yank the fuse to keep the exhaust valves open. Is something like this possible on the 991? I don't have PSE and would love to be able to keep my valves open all the time. Cheapest exhaust mod ever if its possible! Thoughts?

Ignore this. I couldn't find anything with rennlist search, but google lead me to this thread: https://rennlist.com/forums/997-gt2-...ve-open-2.html

Good find. The fuse which controls the exhaust valve is on the driver side, Roby, number 2. However, that fuse also controls the following:

Exhaust flap control,
High-level brake light, spoiler,
Control element cover rear,
Right rear fog light,
Left brake light,
Left reversing light,
Left tail light,
Left daytime running light
15 A

No need to pull fuse, this mod is very easy and can be done in about 5 minutes if you know what you are looking for. No more than 30 minutes if you are new to where everything is on the car.
