Lighten your 2005-08 Porsche 997 Carrera or Carrera S non turbo by replacing the heavy factory mufflers with these straight through tubes. Deleting the mufflers saves 31lb and removing the restriction of the mufflers gives you a +21whp and +21wtq gain and an aggressive Super-Cup Race Car sound, just like the many Rolex Grand Am Race Teams and PCA Drivers already running this system. Simple bolt-in installation, no cutting or welding required.
