Borla Touring Cat-Back Exhaust System (140014) - 1999-2007 Chevy Silverado & GMC Sierra 1500 4.3L, 4.8L, 5.3L Extended Cab Short Bed
Wake up the adventure-ready spirit of your rig with the high-impact Borla Touring Cat-Back Exhaust System. Custom-engineered for 1999 to 2007 Chevrolet Silverado 1500 and GMC Sierra 1500 half-ton trucks (including the 2007 Classic models), this premium full-length exhaust upgrade introduces Borla's most refined acoustic profile: the Touring sound level. Formulated explicitly for truck owners and daily drivers who crave a clean, smooth, and mature exhaust note rather than an overbearing or raspy bark, the Touring muffler is calibrated to give the 4.3L V6, 4.8L Vortec V8, and 5.3L Vortec V8 engines a sophisticated, deeper-than-stock tone under acceleration. This cat-back configuration provides just the right amount of truck-ready performance presence while relying on advanced straight-through internals backed by Borla's official No-Drone Guarantee to keep the cabin completely quiet and drone-free during long highway trips, heavy towing, or daily commuting.
The internal engineering of the Borla 140014 targets key factory flow restrictions by incorporating a high-efficiency single performance layout that channels a 3-inch diameter path through ultra-smooth mandrel bends to ensure maximum exhaust velocity, unleashed horsepower, improved throttle response, and fuel economy. Built completely from premium-grade, aircraft-quality T-304 austenitic stainless steel, this highly durable cat-back system defends permanently against structural degradation, extreme under-truck heat cycling, and severe road salt or mud corrosion. The spent exhaust gases exit through a traditional, clean truck side exit configuration behind the passenger rear tire, featuring a single large 4-inch round, rolled angle-cut long polished T-304 stainless steel tip. Precision CNC-manufactured for an accurate line-to-line bolt-on fitment, this system utilizes all factory hanger locations and is backed by Borla’s legendary lifetime Million-Mile Warranty.
Chassis & Configuration Notes: This cat-back system is engineered specifically for the 143.5-inch wheelbase configuration, which corresponds exclusively to Extended Cab models equipped with a Short Bed (6-foot 7-inch bed length). It is fully compatible with 2WD and 4WD configurations, as well as both Automatic and Manual transmissions. It fits the 1999-2006 model years and the 2007 "Classic" body style. It will **NOT** fit Regular Cab, Crew Cab, or Long Bed configurations without extensive mid-pipe customization.
