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

Your 992 GT3RS is as sharp as a road-going GT3 gets, and it still leaves sound on the table. 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

Porsche changed the rules with the 992. Where 15+ years of 911 GT3 used large side mufflers and a near-universal center muffler, the 992 GT3 and 991.2 Speedster run one gigantic, complicated center muffler with the electronic valves built inside it.

Our answer is modular, because the right balance of weight, sound and performance is different for every owner:

• OPF adapters, cone-shaped with v-band attachment.
• Valve sections shaped like our 997/991 parts and built to take the OE Electronic Valve Actuator — your valves open and close just as they do from the factory, so the car stays civil when you want it to be.
• A muffler of your choosing, which is where most of the volume, drone and tone comes from.

Go bomb-proof with 321 Stainless Steel, drop weight with our sublime Titanium Ultralight, or go all-in on the insane Inconel 625 mini-crack pipe.

It is a foundation, not a one-off: this cat-back is compatible with our forthcoming header system, so Dundon Headers can follow later.

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!
