MBRP S4704AL Cat-Back Exhaust System Dual Rear Exit Aluminized Steel - 2.5 Inch

The MBRP S4704AL Cat-Back Exhaust System transforms your 2018-2021 Kia Stinger 3.3L into a true performance machine. Engineered specifically for both RWD and AWD models, this complete exhaust system delivers measurable power gains, enhanced exhaust tone, and bolt-on installation using factory bezels for a clean, integrated look.

Proven Performance Gains:

MBRP's mandrel-bent tubing design eliminates restrictions found in factory exhaust systems, maximizing exhaust flow for real-world results. Dyno testing shows gains of up to 15 horsepower and 7 ft-lbs of torque, with a 63% increase in exhaust flow compared to stock. Mandrel bending ensures smooth, ripple-free bends that maintain consistent tube diameter throughout, allowing your engine to breathe more efficiently.

Armor Lite Construction:

Built from heavy-gauge aluminized steel, the S4704AL offers excellent durability and corrosion resistance at a value price point. The Armor Lite series is ideal for vehicles in milder, drier climates and provides superior resistance to road debris damage. Despite the budget-friendly price, this system is constructed to the same exacting specifications as MBRP's premium Armor Pro series, with fully sealed tubing that prevents the premature rust-through common in lesser exhaust systems.

Enhanced Sound Without Drone:

MBRP engineers incorporated Helmholtz resonator technology to deliver a deep, aggressive exhaust note outside the vehicle while maintaining a comfortable cabin environment. This system enhances the Stinger's sporty character with an even, refined tone that eliminates the annoying drone that can occur during highway cruising.

Complete System Specifications:

• 2.5-inch mandrel-bent aluminized steel construction
• Dual split rear exit with quad outlet configuration
• Utilizes factory exhaust bezels for seamless integration
• Bolt-on installation with all necessary hardware included
• Helmholtz resonator technology for drone elimination
