Helical valves are an integral part of our Side Muffler Bypass pipes, opening and closing with precision to control the gas flow and optimizing engine back-pressure for improved performance. Helical’s extensive experience in high-volume OEM automotive applications has led to standard features such as an extremely durable pneumatic actuator, precision flat sealing faces inside the valve, stiffening ribs and high-temperature bearings at both ends of the butterfly spindle.\u003c\/p\u003e\n\u003cp style=\"font-weight: 400;\" data-mce-fragment=\"1\" data-mce-style=\"font-weight: 400;\"\u003e\u003cb data-mce-fragment=\"1\"\u003e\u003cstrong data-mce-fragment=\"1\"\u003eO2 BUNGS\u003c\/strong\u003e\u003c\/b\u003e\u003c\/p\u003e\n\u003cp style=\"font-weight: 400;\" data-mce-fragment=\"1\" data-mce-style=\"font-weight: 400;\"\u003eWe relocated the O2 bungs from the collector of the headers to the Side Muffler Bypass Pipes in order to maintain factory-like functionality with our Long Tube Competition Headers - allowing them to read all cylinders while maximizing the performance of the collector. This design will replace our existing SMBP’s allowing you to upgrade to our Long Tube Race Header design at any time in the future.                                               \u003c\/p\u003e\n\u003cp style=\"font-weight: 400;\" data-mce-fragment=\"1\" data-mce-style=\"font-weight: 400;\"\u003e\u003cb data-mce-fragment=\"1\"\u003e\u003cstrong data-mce-fragment=\"1\"\u003eFEATURES\u003c\/strong\u003e\u003c\/b\u003e\u003c\/p\u003e\n\u003cul style=\"font-weight: 400;\" data-mce-fragment=\"1\" data-mce-style=\"font-weight: 400;\"\u003e\n\u003cli data-mce-fragment=\"1\"\u003eFits all Porsche 991 GT3 \/ GT3 RS vehicles (2014-2016)\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eHighest quality Helical valves\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eIncludes O2 bungs for factory like functionality when paired with Fabspeed Long Tube Competition Headers\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eSaves 34 lbs from the rear of the vehicle\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eReplicates aggressive CUP car sound for the street\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003e14-16ga T304 Stainless Steel construction\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eSimple bolt-on installation\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eAll Fabspeed performance products are backed by the Fabspeed Lifetime Warranty\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Fab Speed","offers":[{"title":"Valved","offer_id":39354089210049,"sku":"FS.POR.991GT3.SMBV","price":2546.26,"currency_code":"USD","in_stock":true},{"title":"Non-Valved","offer_id":39354089242817,"sku":"FS.POR.991GT3.SMB","price":1673.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0298\/5610\/4553\/products\/Porsche_997_997_2_991_991_2_GT3_Side_Muffler_Bypass_Pipes_Non-Valved_6-1__43259_1594824237.jpg?v=1615232912","url":"https:\/\/performancecorvettes.com\/products\/fabspeed-porsche-991-gt3-gt3-rs-side-muffler-bypass-pipes-2014-2016","provider":"Performance Corvettes","version":"1.0","type":"link"}
