Auxiliary DB Killer Exhaust System for Porsche 992 GT3 & GT3 RS
Auxiliary exhaust systems (DB Killers) are now mandatory at several racetracks, including Circuit Mont-Tremblant. To meet these requirements, A2B developed a bolt-on solution that requires no permanent modifications, allowing you to continue running your car at its full performance potential while complying with strict track noise regulations.
Many owners of the Porsche 911 GT3 (992) and Porsche 911 GT3 RS (992) struggle to stay within track sound limits—even when using the factory exhaust system.
This DB Killer system offers an effective way to reduce sound levels while maintaining performance, making it ideal for track environments with strict noise restrictions.
