Auxiliary DB Killer Exhaust System for Porsche 992 GT3 Cup

Auxiliary DB Killer exhaust systems are now mandatory at several race tracks, including Circuit Mont-Tremblant. To address this requirement, 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 track sound limits.

Many owners of the Porsche 992 GT3 Cup struggle to stay within noise limits—even with the factory exhaust system. This kit provides an effective and practical way to reduce sound output without altering the vehicle.
