The BBi Autosport Porsche 997 GT3 Exhaust Center Section is a direct replacement for the secondary center muffler. For those who desire a slightly milder exhaust tune, this piece is a great alternative to the Cup-style Side Muffler Bypass Pipes. By retaining stock side mufflers and valves, the factory "sports button" feature is kept to conveniently switch back and forth between the aggressive "sport" mode during spirited driving sessions and the quieter, more civil "non-sport" mode for minimal noise on the highway.
Upgrade your Porsche GT3 with the BBI Autosport Exhaust Center Section to increase airflow, reduce weight, and improve exhaust sound.
