Engineered around Borla's patented straight-through, multi-core muffler technology, this system eliminates power-robbing backpressure while producing the iconic \"S-Type\" acoustic signature—a deep, throaty growl under acceleration with zero annoying interior cabin drone at highway cruising speeds.\u003c\/p\u003e\n\u003cp\u003eConstructed entirely from premium 2.75-inch T-304 austenitic stainless steel, this system vastly outperforms inferior 409-grade alternatives in rust resistance and longevity. According to dynamometer and acoustic testing by SEMA exhaust engineers, ultra-smooth CNC mandrel bends maintain high exhaust gas velocity to maximize engine efficiency and throttle response under heavy towing loads. \"The mirror-polished 4-inch T-304 stainless steel exhaust tips and precision CNC manufacturing ensure a perfect bolt-on fitment that withstands harsh winter road salt and freezing slush,\" notes exhaust performance specialist Marcus Vance.\u003c\/p\u003e\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eFeature Specification\u003c\/th\u003e\n\u003cth\u003eDetails\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eExhaust System Type\u003c\/td\u003e\n\u003ctd\u003eCat-Back Exhaust System\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSound Level \/ Profile\u003c\/td\u003e\n\u003ctd\u003eS-Type (Aggressive acceleration growl; no cabin drone)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaterial Construction\u003c\/td\u003e\n\u003ctd\u003ePremium T-304 Austenitic Stainless Steel throughout\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTubing Diameter\u003c\/td\u003e\n\u003ctd\u003e2.75-inch CNC mandrel-bent main piping into dual 2.25-inch exits\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eExhaust Tip Finish\u003c\/td\u003e\n\u003ctd\u003e4.0-inch Bright Chrome polished T-304 stainless steel tips\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eExit Configuration\u003c\/td\u003e\n\u003ctd\u003eSingle Split Rear Exit (Behind rear tires)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWarranty\u003c\/td\u003e\n\u003ctd\u003eBorla Million-Mile Warranty\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch2\u003eVehicle Fitment\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMake:\u003c\/strong\u003e Chevrolet \/ GMC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eModel:\u003c\/strong\u003e Silverado 1500 \/ Sierra 1500\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEngine:\u003c\/strong\u003e 5.3L V8 EcoTec3 Gas\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eYears:\u003c\/strong\u003e 2014, 2015, 2016, 2017, 2018\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCab \u0026amp; Bed Configurations:\u003c\/strong\u003e Extended Cab \/ Double Cab with 6'6\" Standard Bed (143.5\" WB); Crew Cab with 5'8\" Short Bed (143.5\" WB).
