Chevrolet Silverado / GMC Sierra 1500 ZR2/AT4X 22-27 6.2L Cat-Back Exhaust, S-Type

The Borla S-Type Cat-Back Exhaust System (Part #140914) for the 2022-2023 Chevrolet Silverado 1500 ZR2 and 2022-2023 GMC Sierra 1500 AT4X with the 6.2L V8 engine is designed to enhance both the performance and sound of your truck. Featuring a 3.5" diameter system with dual 2.75" turn-down tailpipes, this exhaust system delivers the iconic Borla S-Type sound—a bold, aggressive tone with no interior drone, perfect for driving enthusiasts who want both performance and comfort.

This system utilizes Borla's patented straight-through and multi-core technology to improve exhaust flow, leading to a noticeable increase in horsepower and torque. The system is built with T-304 stainless steel for superior durability, and ultra-smooth mandrel bends ensure maximum exhaust flow and power. Whether you're off-roading or cruising on the highway, the S-Type Cat-Back Exhaust enhances your driving experience.

For those looking for an even more aggressive sound, Borla's Polyphonic Harmonizer 60680 can be added to upgrade the system to the ATAK® sound level—louder than the S-Type. Additionally, a True Dual Cat-Back® system is available for those who prefer a different configuration.
