Product Description

 

 

The Fabspeed Center Muffler Bypass Pipe removes the restrictive stock center muffler on your 997.2 GT3 / GT3 RS and replaces it with a high‑flow, stainless‑steel bypass system. This upgrade frees up exhaust flow for better throttle response, a deeper and more aggressive exhaust tone, and a lighter rear end — boosting performance character while retaining use‑ability. It’s a direct bolt‑on that delivers a more raw, race‑inspired sound without the fragility issues common to the OEM muffler.

Fitment Notes

  • Fits Porsche 997.2 GT3 and GT3 RS models, model years 2010–2011 (also 2012 in some markets).

  • Designed as a direct replacement for the factory center muffler; uses existing exhaust hangers and mounting points — no cutting or welding required. 

  • Compatible when used with factory side mufflers — retains Sport‑mode exhaust control functionality when side mufflers remain in place.

Included

  • Stainless‑steel bypass pipe assembly replacing the factory center muffler. 

  • High‑durability mandrel‑bent 14‑16 gauge T304 stainless tubing.

  • 4″ exhaust tip outlets (options for different finishes) or the ability to reuse OEM tips. 

  • All necessary hardware for bolt‑on installation using existing mounting points.

Product Specs

  • Material: 14–16 ga T304 stainless steel for corrosion resistance and durability under heat/stress. 

  • Power Gains: Approximately +10 wheel horsepower (whp) and +6 ft‑lb torque, with improved throttle response. 

  • Weight Savings: Roughly 10 lbs removed from rear compared to OEM center muffler, reducing rear‑end mass for improved dynamics.

  • Exhaust Note: More aggressive, open exhaust tone; “talk‑pipe” design blends left/right banks for a smooth, unified sound signature under load.

Product Features

  • Improved Exhaust Flow & Throttle Response — By eliminating the restrictive center muffler, exhaust gases flow more freely, allowing the engine to rev and respond faster under load.

  • Enhanced Exhaust Character & Sound — Produces a deeper, more aggressive exhaust note with a race‑inspired tone — ideal for track days or spirited driving.

  • Weight Reduction for Better Handling — Shedding ~10 lbs from the rear helps reduce unsprung/rotating mass and improve overall vehicle balance and responsiveness.

  • Bolt-On, OEM‑Compatible Fitment — Installs using factory mounting points and hardware; no welding or custom fabrication required — straightforward install for DIY or shop.

  • Durable Stainless Construction — Built to resist corrosion and heat stress, ensuring longevity and consistent performance under track or street use.

  • Maintain Sport Mode Functionality (with Side Mufflers) — When used with stock or aftermarket side mufflers, the original Sport‑mode exhaust control remains functional, giving flexibility in sound and driveability.
