Borla Touring Dual Split Rear-Exit Cat-Back Exhaust System with Single Round Polished Tips (14824) - 1999-2007 Chevy Silverado & GMC Sierra 1500 4.3L, 4.8L & 5.3L
Wake up the high-performance spirit of your classic half-ton truck with the high-impact Borla Touring Cat-Back Exhaust System. Custom-engineered for 1999 to 2007 Chevrolet Silverado 1500 and GMC Sierra 1500 models, this premium exhaust upgrade introduces Borla's refined acoustic profile: the mellow Touring sound level. Formulated explicitly for driving enthusiasts and truck owners who crave an upgraded, sport-tuned exhaust note without overwhelming volume, this system is calibrated to give the V6 or Vortec V8 engine a clean, deep rumble. This configuration delivers a throatier 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 towing, daily commuting, or weekend projects.
The internal engineering of the Borla 14824 targets key factory flow restrictions by incorporating an upgraded high-efficiency dual performance layout. The design features a high-flow single 3-inch primary pipeline leading into the muffler that branches out into smooth dual 2.25-inch mandrel-bent tailpipes. At its core, this assembly features Borla's patented straight-through multi-core muffler technology, which increases exhaust gas velocity and scavenging efficiency to unlock hidden horsepower, sharper throttle response, and enhanced power delivery. 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 winter road salt. Precision CNC-manufactured for an accurate line-to-line bolt-on fitment, this system utilizes existing factory mounting positions and is backed by Borla’s legendary lifetime Million-Mile Warranty.
Polished Round Dual Split Styling: This premium dual-exit kit updates the rear styling of your truck with an aggressive dual split rear layout. The system terminates with a single 4-inch round, rolled edge angle-cut bright chrome on T-304 stainless steel exhaust tip on each tailpipe location. Exiting symmetrically behind each rear wheel, these oversized tips provide a striking, classic truck accent that commands respect on the road.
