The GT3 Center Muffler Reinforcement Brace is designed to extend the fatigue life of any and ALL GT3 OEM Porsche factory center mufflers. Each and every Porsche 997GT3 2006 to 2019 GT3/ GT3RS stainless steel and Titanium OEM muffler’s metal skin fractures due to an “oil can” effect. The varying internal pressures generated by the exhaust gases cause a repeated expansion and contraction leading to a classic fatigue failure. Big Old Backfires and explosions in a GT3 are common too and hurt muffler cases. Its common knowledge that many Porsche GT3 center mufflers are breaking/ exploding/fracturing if the cars are driven and really driven at Track Events and enthusiast events. The Fabspeed brace is designed to reduce the magnitude of this deflection resulting in a longer service life. This small modification can save you a very expensive trip to the dealer and potentially $2500 which is the cost of replacement for a factory OEM Muffler or over $6000 for the Titanium GT3RS/ 911R center muffler.
