Product Description

 

 

The Fabspeed Side Muffler Bypass Pipes for the Porsche 997.2 Carrera (2009–2012) are a high‑flow rear exhaust upgrade that removes the restrictive stock side/secondary mufflers to unleash a more aggressive exhaust note while significantly increasing efficiency and reducing weight. By eliminating muffler restriction, these bypass pipes free up exhaust flow for measurable power gains and a louder, motorsport‑inspired soundtrack without modifying the center muffler section. CNC mandrel‑bent T304L stainless steel construction delivers strength, optimal flow, and long‑term durability, while compatibility with factory or upgraded exhaust tips ensures a seamless aesthetic finish. Ideal as a standalone upgrade or part of a complete exhaust overhaul, this set gives the flat‑six more voice and performance.
