The bbi autosport Porsche 991 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 our 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.
