Borla S-Type Cat-Back Exhaust System with 4-Inch Black Chrome Tips (140571BC) - 2014-2018 Silverado & Sierra 1500 6.2L V8
Wake up the high-performance spirit of your truck with the high-impact Borla S-Type Cat-Back Exhaust System. Custom-engineered for 2014 to 2018 Chevrolet Silverado 1500 and GMC Sierra 1500 models, this premium full-length exhaust upgrade introduces Borla's legendary acoustic profile: the classic S-Type sound level. Formulated explicitly for driving enthusiasts and truck purists who crave an aggressive, sport-tuned exhaust note under acceleration, this system is calibrated to give the high-output 6.2L V8 engine a bold, crisp, and high-impact growl. This configuration delivers a commanding exterior acoustic presence while relying on advanced straight-through internals backed by Borla's official No-Drone Guarantee to keep the cabin completely comfortable and drone-free during highway cruising, daily towing, or heavy work commutes.
The internal engineering of the Borla 140571BC targets key factory flow restrictions by incorporating an upgraded high-efficiency performance layout featuring a massive 3.5-inch inlet diameter that transitions smoothly into dual 2.25-inch exit pipes out of the muffler body. This performance architecture utilizes ultra-smooth mandrel-bent performance tubing and patented multi-core internal geometry that maximizes exhaust velocity and optimizes scavenging to unlock hidden horsepower, sharper throttle response, and enhanced fuel economy across the entire powerband. Designed to route flawlessly along the undercarriage, it leaves plenty of extra clearance for daily hauling and is tailored exclusively to match specific 143.5-inch wheelbase configurations. Built completely from premium-grade, aircraft-quality T-304 austenitic stainless steel, this highly durable cat-back assembly defends permanently against structural degradation, intense under-car heat cycling, and severe corrosion. The spent exhaust gases exit through a distinctive truck single split rear exit configuration finished with premium black chrome visual styling on dual 4-inch round, rolled edge angle-cut T-304 stainless steel tips. Precision CNC-manufactured for an accurate line-to-line bolt-on fitment, this system utilizes all factory mounting positions and is backed by Borla’s legendary lifetime Million-Mile Warranty.
Chassis & Configuration Notes: This performance cat-back system is engineered specifically for 2-wheel drive (2WD) and 4-wheel drive (4WD) regular-duty trucks running the 143.5-inch wheelbase layout.
