STILLEN 2010-2016 Hyundai Genesis Coupe [BK38] Cat-Back Exhaust System - 508185

The STILLEN Stainless Steel Cat-Back Exhaust System for the 2010–2016 Hyundai Genesis Coupe V6 (BK38) is engineered to deliver the perfect balance of performance, sound, and refinement. Designed for drivers who want measurable power gains without sacrificing cabin comfort, this system enhances both driving excitement and visual appeal.

Constructed entirely from premium 304 stainless steel, this cat-back exhaust system offers exceptional durability, corrosion resistance, and long-term reliability. The system features 2.5-inch mandrel-bent piping to smooth exhaust flow, paired with free-flowing mufflers and resonators that reduce backpressure and unlock additional performance. The result is a verified gain of up to 9 horsepower at the wheels along with improved torque delivery.

Sound tuning was a top priority during development. At idle and during steady cruising, the exhaust maintains a mild, refined tone, making it ideal for daily driving. Under throttle, the system transforms with a deep, aggressive exhaust note that enhances the Genesis Coupe’s sporty character—without the unwanted drone often found in aftermarket systems.

Visually, the STILLEN Cat-Back Exhaust delivers a bold, performance-focused upgrade. Polished quad 3.5-inch stainless steel tips, along with polished mufflers and end pipes, fill the factory exhaust cutout perfectly and provide a clean, aggressive rear-end appearance.

As with all STILLEN exhaust systems, this kit was developed to meet strict performance, sound quality, and durability standards. Backed by a Limited Lifetime Warranty, it’s a premium upgrade for Genesis Coupe owners who want performance they can feel, sound they can enjoy, and quality they can trust.
