A Record-Breaking Sale: The 997.1 GT3 RS Market Reaches New Heights

 

The Porsche 997.1 GT3 RS has always been a highly desirable collector’s car, but recently, the market witnessed something extraordinary—a 7,000-mile, one-owner 2008 GT3 RS sold for a staggering $395,997 on Bring a Trailer.

 

This isn’t just an impressive sale—it’s a game-changing moment for Porsche collectors. It signals that the first-generation 997 RS is officially a blue-chip Porsche investment, joining the ranks of the most sought-after GT models.

 

But what makes this particular GT3 RS so valuable?

• Low mileage: With just 7,000 miles, this RS is practically showroom fresh.

• Rare spec: Ordered after the standard allocation period, making it even more exclusive.

• Manual gearbox: A six-speed transaxle paired with a Mezger engine —  Porsche perfection.

• Preserved yet upgraded: The new owner whant made one crucial modification—a high-performance exhaust upgrade featuring Dundon Motorsports’ 997.1 Street Headers.

 

This sale isn’t just about a record-breaking price—it’s about how well-preserved, well-optioned, and properly modified examples are shaping the future of the 997 market.


The Mezger Masterpiece: Why the 997.1 GT3 RS is Special

 

The 3.6-liter Mezger flat-six under the hood of the 997.1 GT3 RS is one of Porsche’s most celebrated engines—an evolution of the motorsport-derived Mezger block that powered the Le Mans-winning GT1 race car.

 

This Green (J5) 997.1 GT3 RS wasn’t just well-preserved—it was perfectly optioned for performance. But one key upgrade made it stand out even more: the installation of Dundon Motorsports’ Street Headers.

 

Dundon Motorsports Street Headers: The Ultimate Upgrade for the Mezger Engine

 

For a track-focused Porsche like the 997.1 GT3 RS, unlocking the full potential of the engine requires optimizing exhaust flow and response. That’s why the owner of this car made a smart choice—installing Dundon Motorsports’ 997.1 Street Headers.

 

Why Dundon’s Street Headers Matter:

✔ Better exhaust scavenging → More power, improved torque curve.

✔ Weight savings → Reducing rear-end mass for sharper handling.

✔ Sharper throttle response → Enhanced driving feel and control.

✔ Refined Mezger sound → Amplifies the naturally aspirated scream without excessive drone.

 

This $400K sale proves that performance modifications—when done right—don’t hurt value. They enhance it. A properly tuned GT3 RS with carefully selected upgrades is now just as desirable (if not more) than a fully stock, untouched example.

 

But this isn’t the first time a Dundon-enhanced 997.1 GT3 RS has made waves in the Porsche world.
