Our goal was to engineer a replacement that not only eliminates these durability concerns but also elevates performance, sound, and overall quality beyond the factory design.\u003c\/p\u003e \u003cp\u003eDrawing on more than 30 years of experience engineering exhaust systems for Porsche and other exotic performance vehicles, Fabspeed developed a completely reimagined titanium muffler that delivers exceptional strength, significant weight savings, and superior exhaust flow without compromising the refined character of the GT3.\u003c\/p\u003e \u003cp\u003eTo maximize performance, we increased the valve-open tubing diameter to 2.75 inches (70 mm) - the optimal size for the naturally aspirated GT3 engine. This provides the ideal balance of low exhaust restriction while maintaining high exhaust gas velocity, preserving the unmistakable high-frequency GT3 exhaust note inspired by the legendary Porsche GT3 Cup race cars.\u003c\/p\u003e \u003cp\u003eAt the heart of the system is Fabspeed's signature investment-cast X-pipe, engineered to optimize exhaust scavenging by efficiently merging both cylinder banks without introducing unnecessary turbulence or restriction. The result is improved cylinder evacuation, enhanced mid-range torque, and a smoother, more responsive power delivery.\u003c\/p\u003e \u003cp\u003eTo preserve the refined driving characteristics expected from a GT3, we carefully replicated Porsche's seven-chamber internal muffler architecture. This delivers an exhaust note remarkably close to OEM with the valves closed while remaining completely drone-free - even when paired with catless race headers. With Porsche Sport Exhaust (PSE) activated, the titanium construction and optimized internal flow produce a more aggressive, smoother, and higher-pitched exhaust note without becoming intrusive.\u003c\/p\u003e \u003cp\u003eWhen combined with our Side Muffler Bypass Pipes, this system creates the ultimate emissions-compliant GT3 exhaust package.\u003c\/p\u003e \u003cp\u003eMost importantly, this titanium muffler has been engineered for long-term durability and is designed to eliminate the cracking and structural failures commonly experienced with the factory muffler.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eSound:\u003c\/strong\u003e\u003c\/p\u003e \u003cp\u003eThe Rennsport Titanium Muffler retains the refined OEM character while delivering a more engaging driving experience. With the PSE valves open, the exhaust becomes noticeably louder, smoother, and sharper in tone thanks to the optimized flow path and signature Fabspeed X-pipe, producing the unmistakable motorsport-inspired sound expected from a GT3.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003ePerformance:\u003c\/strong\u003e\u003c\/p\u003e \u003cp\u003eOn our Porsche 991.1 GT3 RS development vehicle, paired with our Side Muffler Bypass Pipes, the Rennsport Titanium Muffler produced gains of 27 lb-ft of torque at 3,200 RPM. From 2,900 RPM through 5,700 RPM, the system generated gains of 10 wheel horsepower or more, with peak output increasing from 446 WHP to 454 WHP - an improvement of 8 wheel horsepower (approximately 9 horsepower at the crank).\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003eFits all Porsche GT3 and GT3 RS models from the 997.1 to the 991.2 (2006-2019) worldwide\u003c\/li\u003e \u003cli\u003eConstructed entirely from premium aerospace-grade titanium for exceptional strength, corrosion resistance, and significant weight reduction\u003c\/li\u003e \u003cli\u003eLightweight titanium construction improves vehicle dynamics while maintaining outstanding durability under extreme temperatures\u003c\/li\u003e \u003cli\u003eDesigned from precise 3D scans of the OEM muffler to ensure perfect bolt-on fitment\u003c\/li\u003e \u003cli\u003eEngineered to eliminate the cracking and structural failures commonly associated with the factory muffler\u003c\/li\u003e \u003cli\u003eIncorporates Fabspeed's signature investment-cast X-pipe for superior exhaust scavenging and maximum flow\u003c\/li\u003e \u003cli\u003eProduces gains of +27 lb-ft of torque and +16 WHP (approximately +18 HP at the crank) when paired with Fabspeed Side Muffler Bypass Pipes\u003c\/li\u003e \u003cli\u003eAvailable with three premium exhaust tip options\u003c\/li\u003e \u003cli\u003eFully retains factory Porsche Sport Exhaust (PSE) valve functionality\u003c\/li\u003e \u003cli\u003eGuaranteed Check Engine Light-free operation\u003c\/li\u003e \u003cli\u003eCat-back design remains emissions compliant in all 50 states and international markets\u003c\/li\u003e \u003cli\u003ePrecision engineered and manufactured in-house at Fabspeed Motorsport in Fort Washington, Pennsylvania\u003c\/li\u003e \u003cli\u003eSimple direct bolt-on installation with no cutting or welding required\u003c\/li\u003e \u003cli\u003eBacked by the Fabspeed Motorsport Lifetime Warranty\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003e\u003cstrong\u003eNOTE:\u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003eRequires OEM gaskets and hardware to be reused\u003c\/li\u003e \u003cli\u003eIf they are not available here are the necessary part numbers.\u003c\/li\u003e \u003cli\u003e2x Muffler band straps (99711111970)\u003c\/li\u003e \u003cli\u003e2x Bolt for muffler band strap (90006736201)\u003c\/li\u003e \u003cli\u003e2x Each Side Muffler to Center Muffler Gaskets (99711156390, 99711156190)\u003c\/li\u003e \u003c\/ul\u003e","brand":"Fabspeed Motorsport","offers":[{"title":"Satin Black","offer_id":47875201925276,"sku":"FS.POR.GT3.RSMB","price":6295.95,"currency_code":"USD","in_stock":true},{"title":"Carbon Fiber","offer_id":47875201958044,"sku":"FS.POR.GT3.RSMCF","price":6295.95,"currency_code":"USD","in_stock":true},{"title":"Polished Stainless Steel","offer_id":47875201990812,"sku":"FS.POR.GT3.RSMP","price":6195.95,"currency_code":"USD","in_stock":true},{"title":"Brushed Stainless Turn Down","offer_id":47875202023580,"sku":"FS.POR.GT3.RSMTD","price":6195.95,"currency_code":"USD","in_stock":true},{"title":"Titanium","offer_id":47875202056348,"sku":"FS.POR.GT3.RSMTI","price":6295.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0473\/3206\/5436\/files\/DSC03829__67312.1785225687.jpg?v=1792261963","url":"https:\/\/daroracing.com\/products\/fabspeed-porsche-gt3-gt3-rs-titanium-rennsport-muffler-2006-2019","provider":"Daro Racing","version":"1.0","type":"link"}
