Borla Touring Cat-Back Exhaust System with 4-Inch Polished Tips (140341) - 2009-2013 Silverado & Sierra 1500 4.8L, 5.3L & 6.0L V8
Wake up the high-performance spirit of your truck with the high-impact Borla Touring Cat-Back Exhaust System. Custom-engineered for 2009 to 2013 Chevrolet Silverado 1500 and GMC Sierra 1500 models, this premium full-length exhaust upgrade introduces Borla's legendary acoustic profile: the mellow Touring sound level. Formulated explicitly for driving enthusiasts and truck purists who crave a highly sophisticated, deep exhaust note under acceleration without excessive volume, this system is calibrated to give the 4.8L, 5.3L, and 6.0L V8 engines 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 commuting, or heavy towing.
The internal engineering of the Borla 140341 targets key factory flow restrictions by incorporating an upgraded high-efficiency performance layout featuring a 2.75-inch diameter main pipe that splits into dual 2.25-inch mandrel-bent tailpipes. This performance architecture utilizes ultra-smooth mandrel bends and a straight-through multi-core configuration that maximizes exhaust velocity 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 flow capacity for additional aftermarket performance modifications down the road. 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 split side configuration featuring dual 4-inch round, rolled edge angle-cut polished T-304 stainless steel tips exiting behind each rear wheel. 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 cat-back system is engineered specifically for the 2-Wheel Drive (2WD) and 4-Wheel Drive (4WD) automatic and manual transmission configurations of the 2009 to 2013 GM 1500 truck platform on a 143.5-inch wheelbase. It fits two specific configurations: Extended Cab models equipped with a 6-foot 7-inch Standard Bed, and Crew Cab models equipped with a 5-foot 9-inch Short Bed. It will not accommodate alternative wheelbase or bed lengths.
