Product Description

The Borla 140736 S-Type Cat-Back Exhaust System is engineered specifically for the 2018-2021 Kia Stinger GT equipped with the 3.3 L V6 turbo engine. By replacing the factory exhaust from the rear of the catalytic converters, this system opens up flow via mandrel-bent 2.25" T-304 stainless steel tubing, and incorporates a merge X-pipe and Borla's Polyphonic Harmonizer technology to create a deep, rich exhaust note with minimal interior drone.

Installation is direct-fit and reuses the factory tip outlets to maintain a clean OEM appearance. While tips are not included, Borla offers optional compatible polished tips to further customize the end aesthetic. Designed for enthusiasts seeking a premium quality, high-end exhaust upgrade that enhances sound, durability and performance for the Stinger GT, this system is backed by Borla's Million-Mile Warranty for long-term confidence.
