Description:

Dundon Street Header/Lifetime Muffler
Power Package Exhaust
(2010-2011 997.2 GT3RS, GT3)

Loud Muffler with Ti tips

  • The gold standard for the 997.2 GT3/RS platform. Best sound I have ever heard.
  • NO CEL.
  • MINT conditions. In use for 300 miles. No track use. Full warranty in place. Purchased 4 months ago. 
  • Located in So. Florida. Local pickup or shipping is available. 
  • Purchased it for $15K.
  • Selling because I have sold the car. Happy with the quality and the sound. Nothing wrong with it.
  • Price $9990 OBO


Key Features and Benefits
  • Performance: Optimized for power, typically increasing torque and horsepower through better flow and scavenging, often paired with a Cobb AP Pro Tune.
  • Muffler Options:
  • Loud: Maximizes flow for high-power applications with a "wicked" flat-six sound.
  • Headers: Long-tube design, typically 321 Stainless Steel, featuring catalytic converters to meet "street" requirements while improving over OEM headers.
  • Durability: The muffler is designed for longevity, featuring 321 stainless steel construction, and is designed to handle track abuse.



Key Considerations
  • Weight: The system offers a lighter alternative to the stock center muffler system.
  • Sound: The system aims to eliminate cabin drone while providing a more aggressive, raw sound compared to the stock exhaust.
  • The package is a comprehensive solution specifically tailored to the 997.2 GT3RS, aimed at improving both street usability and track performance.

@revtech911 hey, given that there have been three unique prices for this item -- two here, and one on eBay -- I'm a little sketched out as this is an old pattern we used to see from scammers a couple years ago.

Please reply here with a photo of the exhaust with a piece of paper having today's date and your username hand-written on it by EOD.
