Turn your S58 setup into an absolute weapon. The factory exhaust note on the G8x goes soft way too early—this PCZ Performance 3.5'' Valved Catback fix that instantly. Engineered around a custom Equal Length Z-Pipe, this setup kills that cheap, high-rpm rasp and delivers a clean, high-pitched acoustic profile that actually sounds like an M car should.
Need to sneak out at 6 AM without blowing up the neighborhood chat? Keep the valves shut for a quiet, drone-free daily mode. Ready to let it rip? Hit the included wireless remote to open the valves up and release full straight-through flow.
Finished with custom-embossed PCZ branding stamped right onto the main muffler canister, built from heavy-duty T304 stainless steel, and packed with thick quad carbon tips—it's built to lock in the ultimate OEM+ stance.
