Description

The Borla S-Type Cat-Back Exhaust System is custom-engineered for the 2025-2026 Kia K5 GT equipped with the 2.5L 4-cylinder turbocharged engine. This high-performance system features a 2.75-inch main pipe diameter that transitions into dual 2-inch piping, specifically tuned to optimize exhaust flow and engine efficiency. A hallmark of this kit is Borla's patented Polyphonic Harmonizer technology, which utilizes internal pipes of varying lengths and diameters to create multiple exhaust notes that harmonize into a clean, rich, and full-bodied sound. The S-Type sound level provides a sportier, more aggressive roar than the factory setup while remaining perfectly balanced for daily driving.

Constructed from premium T-304 austenitic stainless steel, this exhaust is built to withstand high heat and resist corrosion far better than standard T-400 series or aluminized steel alternatives. The system is designed with ultra-smooth mandrel bends to ensure maximum power gains and a "No-Drone" guarantee for a comfortable cabin experience at all speeds. Finishing the look is a set of quad 4-inch round tips in a sleek Black Chrome finish, providing a stealthy, high-end performance aesthetic. As a direct bolt-on replacement, it utilizes factory mounting points for a hassle-free installation and is backed by Borla's industry-leading Million-Mile Warranty.
