Product Description

 

 

Transform the sound and responsiveness of your Porsche 997 Carrera with the Fabspeed Muffler Bypass Pipes. This lightweight exhaust upgrade completely replaces the heavy factory mufflers with straight-through tubing, delivering a dramatic increase in exhaust volume and a raw, motorsport-inspired flat-six soundtrack. In addition to the aggressive sound, the reduced backpressure helps improve throttle response and power delivery throughout the RPM range. By removing approximately 31 pounds from the rear of the vehicle, this system also contributes to improved weight distribution and handling feel. Designed as a direct bolt-on installation, the Fabspeed Muffler Bypass Pipes are an excellent choice for enthusiasts seeking maximum sound, reduced weight, and noticeable performance gains from their Porsche 997 Carrera.
