Product details

Fabspeed’s Side Muffler Bypass Pipes replace the side silencers on the 2006–2009 Porsche 997 GT3 and GT3 RS. The valved and non-valved choices allow different exhaust-flow arrangements, so existing controls and the desired sound behavior should be checked before selecting a version. Fabspeed Motorsport engineers sports-car exhaust, intake and ECU-tuning systems in Fort Washington, Pennsylvania. Its development work includes dynamometer testing and evaluation on the road and racetrack.

Technical Details

  • Product family reference: FS.POR.997GT3.SMBX
  • T304 stainless steel in 14–16-gauge construction.
  • Choice of open or Helical-valved side sections.
  • Pneumatically actuated valves on the valved assembly.
  • Factory-style bolt-on installation.
