Recognizing the common issue of OEM mufflers cracking, breaking, and blowing out, especially the titanium ones on GT3 RS cars, Fabspeed designed a replacement that addresses this while improving upon the original design.\u003c\/p\u003e\n\u003cp data-sourcepos=\"5:1-5:584\"\u003eThe valve-open tubing diameter was increased to 2.75 inches \/ 70mm, identified as the optimal size for GT3 engines to ensure low restriction while maintaining high velocity and the signature high-pitched GT3 CUP car sound. Fabspeed's signature investment-cast X-pipe was integrated for optimal exhaust scavenging, merging the two cylinder banks without creating any flow restriction. To replicate the factory muffler's exhaust note and eliminate drone, Porsche’s 7-chamber design was mimicked. This results in a completely drone-free muffler, even when used with catless race headers.\u003c\/p\u003e\n\u003cp data-sourcepos=\"7:1-7:17\"\u003e\u003cstrong\u003eKey Features:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul data-sourcepos=\"9:1-18:63\"\u003e\n\u003cli data-sourcepos=\"9:1-9:36\"\u003eGuaranteed to NEVER break or fail.\u003c\/li\u003e\n\u003cli data-sourcepos=\"10:1-10:49\"\u003eConstructed from CNC-cut T304L stainless steel.\u003c\/li\u003e\n\u003cli data-sourcepos=\"11:1-11:72\"\u003eDesigned from 3D scans of the OEM muffler for perfect bolt-on fitment.\u003c\/li\u003e\n\u003cli data-sourcepos=\"12:1-12:48\"\u003eWill not break or crack like OEM GT3 mufflers.\u003c\/li\u003e\n\u003cli data-sourcepos=\"13:1-13:89\"\u003eIncorporates Fabspeed's signature cast X-pipe for superior flow and exhaust scavenging.\u003c\/li\u003e\n\u003cli data-sourcepos=\"14:1-14:137\"\u003eWhen paired with Fabspeed's Side Muffler Bypass Pipes, this muffler adds \u003cstrong\u003e+27 ft\/lbs of TQ\u003c\/strong\u003e and \u003cstrong\u003e+16 WHP (or +18 HP at the crank)\u003c\/strong\u003e.\u003c\/li\u003e\n\u003cli data-sourcepos=\"15:1-15:36\"\u003e3 different tip options available.\u003c\/li\u003e\n\u003cli data-sourcepos=\"16:1-16:78\"\u003eCompletely retains PSE (Porsche Sport Exhaust) valved exhaust functionality.\u003c\/li\u003e\n\u003cli data-sourcepos=\"17:1-17:35\"\u003eNo Check Engine Light guaranteed.\u003c\/li\u003e\n\u003cli data-sourcepos=\"18:1-18:63\"\u003eSimple bolt-on installation, requiring no cutting or welding.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cdiv class=\"chat-history-scroll-container\" id=\"chat-history\"\u003e\n\u003cdiv id=\"96c9dcc97945b7df\" class=\"conversation-container message-actions-hover-boundary tts-removed ng-star-inserted\"\u003e\n\u003cdiv\u003e\n\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\n\u003cdiv id=\"feedback-form-17\" class=\"feedback-form-turn-index\"\u003e\u003c!----\u003e\u003c\/div\u003e\n\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\n\u003c\/div\u003e\n\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\n\u003c\/div\u003e\n\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\n\u003c\/div\u003e\n\u003cp\u003e\u003c!----\u003e\u003c\/p\u003e\n\u003cp\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c\/p\u003e\n\u003cp\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c\/p\u003e\n\u003cp\u003e\u003c!----\u003e\u003c!----\u003e\u003c\/p\u003e\n\n\u003cp data-sourcepos=\"3:1-3:13\"\u003e\u003cstrong\u003eReturns subject to a 25% restocking fee.\u003c\/strong\u003e\u003c\/p\u003e","brand":"Fabspeed","offers":[{"title":"Carbon Fiber","offer_id":40859242004538,"sku":"FS.POR.991GT3.RSMC","price":4946.48,"currency_code":"USD","in_stock":true},{"title":"Satin Black","offer_id":40859242037306,"sku":"FS.POR.991GT3.RSMB","price":4946.48,"currency_code":"USD","in_stock":true},{"title":"Polished Stainless Steel","offer_id":40859242070074,"sku":"FS.POR.991GT3.RSMP","price":4946.48,"currency_code":"USD","in_stock":true},{"title":"Brushed Stainless Turn Down","offer_id":40859242102842,"sku":"FS.POR.991GT3.RSMTD","price":4946.48,"currency_code":"USD","in_stock":true},{"title":"Titanium","offer_id":40859242135610,"sku":"FS.POR.991GT3.RSMTI","price":4946.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0549\/4846\/2650\/files\/Porsche-Rennsport-Muffler-911-2014-2016-FS-POR-991.jpg?v=1747948960","url":"https:\/\/sierramadrecollection.com\/products\/porsche-rennsport-muffler-911-2014-2016-fs-por-991gt3-rsmc","provider":"Sierra Madre Collection","version":"1.0","type":"link"}
