Active Exhaust Modes
The valves are closed in quiet mode and completely open in normal, sport, and track modes.

Active Exhaust Modes
The valves are only working in 2 positions... fully closed and fully opened. I guess that's quiet mode and track mode.

No, I don't know how to do that. I hear a click when I put it in or out of quiet mode and quiet mode works fine.

I have a 2025 GT Premium with active exhaust. When I roll through the modes, Normal, Sport, and Track all sound the same. Any thoughts? TIA.

RTR hood vent installed!
I've been considering one of these, but because my car is Shadow Black, I'm afraid the matte black might not look as good as the gloss black. Anyone tried it on a black car?
