he Borla 141036 S-Type Cat-Back exhaust system is designed specifically for the 2025–2026 Kia K5 GT-Line equipped with the 2.5L 4-cylinder engine, automatic transmission, and all-wheel drive.
Borla tunes this 2.25-inch Cat-Back system to deliver a sportier exhaust note than stock while remaining refined during normal driving. The S-Type sound level is intended to provide a noticeable performance tone without the more aggressive character associated with Borla’s ATAK systems. Borla also designs the system for a drone-free cruising experience.

S-Type Sound
Borla positions the S-Type sound level as a sportier upgrade over stock while maintaining a refined character.
T-304 Stainless Steel Construction
The 141036 system is manufactured from premium T-304 austenitic stainless steel for durability and corrosion resistance.
Borla uses mandrel bends to maintain smooth internal exhaust flow through changes in tubing direction, while CNC manufacturing helps provide accurate fit and consistency from system to system.
Exhaust Flow and Performance
Borla’s Cat-Back systems use straight-through and multi-core exhaust technology designed to improve exhaust velocity and reduce restriction compared with the original system.
The 2.25-inch tubing is specifically tuned for the K5 GT-Line’s 2.5L engine rather than being a generic universal exhaust configuration.
