Product Details

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 BBI's 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. 


  • Delivers deep aggressive exhaust sound
  • Internal crossover bypass design
  • Significant weight reduction
  • Retains Sports Exhaust Button function
  • TIG welded T304 brushed stainless steel construction
  • Factory primary side mufflers & catalytic converters are all retained
  • Direct bolt on replacement
  • 50 State 100% emissions legal
  • Will not void warranty
  • Optional black ceramic coat finish available
  • Made in USA
