992 GT3RS Exhaust: Valved Cat-Back Exhaust System (Non-EU Version)

The 992 GT3RS shares its exhaust architecture with the 992 GT3 and the 991.2 Speedster, and it is a drastic departure from the last 15+ years of 911 GT3. The large side mufflers are gone, so is the nearly universal center muffler; in their place sits a gigantic, complicated center muffler with the electronic valves built into it.

Weight, sound and performance are a personal trade-off, so we made the system modular rather than picking for you. It is built from three elements:

• OPF adapters — cone-shaped, with v-band attachment.
• Valve sections that look like our 997/991 parts but accept the OE Electronic Valve Actuator, so your valves behave exactly like stock.
• The muffler itself, which drives most of the volume, drone and tone.

From there it is your call: bomb-proof 321 Stainless Steel, the sublime Titanium Ultralight, or the frankly insane Inconel 625 mini-crack pipe.

And nothing here is a dead end — this cat-back is compatible with our forthcoming header system, so you can start with the cat-back today and add Dundon Headers later.
