The Hooker BlackHeart Exhaust System is precision-engineered to unleash performance and deliver a bold, refined exhaust note. Its cab-rearward X-pipe and dual straight-through mufflers maximize exhaust scavenging for noticeable power gains while minimizing in-cabin resonance. Constructed from 18-gauge, 2.5-inch mandrel-bent 304 stainless steel, it offers up to 32% weight reduction—saving approximately 22 lbs compared to the factory exhaust. The dual 4" angle-cut, polished stainless steel tips, laser-etched with the Hooker BlackHeart logo, provide a high-end look and lasting finish. Each system is 100% hand-welded to ensure superior strength and craftsmanship. Utilizing factory mounting points, it installs easily for a perfect fit and performance upgrade that enhances both sound and style.
