992 GT3 Exhaust: Valved Cat-Back System (EU/RoW Version)

Your 992 GT3 gets nearly everything right. The sound isn't one of them. This is the EU/RoW fitment of Dundon Motorsports' Cat-Back Exhaust System: No CEL, No Codes, No tune required, just pure sound!

Photographs are illustrative only, production parts will look different.

Technical Description

Our 992 cat-back replaces the factory system in three sections, and each one does a specific job:

• OPF adapters: cone-shaped transitions with v-band attachment.
• Valve sections: familiar in shape to our 997/991 parts, but built around the OE Electronic Valve Actuator, so the valves keep working exactly as they do from the factory.
• Muffler: the component that decides how loud, how clean and how characterful the car sounds.

There is a reason it is built this way. The 992 GT3 and 991.2 Speedster broke with 15+ years of 911 GT3 exhaust design — no large side mufflers, no conventional center muffler, and instead one enormous, complex center muffler with the electronic valves integrated. Weight, sound and performance are deeply subjective on a car like this, so we would rather give you the choice than make it for you.

Muffler options run from the reliable, bomb-proof 321 Stainless Steel unit, through our sublime Titanium Ultralight, to the insane Inconel 625 mini-crack pipe.

Buy now, build later: the cat-back is designed to work with our forthcoming header system, so Dundon Headers can be added down the road.

Technical Description

The 992 GT3 and 991.2 Speedster mark a drastic departure in exhaust configuration when compared with the last 15+ years of 911 GT3. Gone are the large side mufflers and nearly universal center muffler. The 992 platform has a gigantic and complicated center muffler that has the electronic valves built in.

To find the best combination of weight, sound and performance is an incredibly subjective thing. With that in mind, we have created a modular system that includes the following:

-OPF Adapters (cone-shaped pieces with v-band attachment).

-Valve Sections (these look like the 997/991 valve sections, but accept the OE Electronic Valve Actuator, so your valves will operate just like stock).

-Muffler Replacement (many options to choose from, this will have the biggest impact on volume, drone, and tone).

With options for every driver, Dundon has the system for you! Everything from reliable, bomb-proof 321 Stainless Steel muffler, or our sublime Titanium Ultralight muffler to the insane Inconel 625 mini-crack pipe, you can pick the perfect pairing for your needs.

These systems will be compatible with our forthcoming header system. Yes, you read that correctly: buy the cat-back, and you can add Dundon Headers later!
