Constructed from 3” 18-gauge stainless steel, the BlackHeart Cat-Back Exhaust with Dual Mode Mufflers NPP for 2014–2015 C7 Corvette from Hooker produces a mellow, throaty tone when the valve is closed and aggressive race attitude when the value is open. Notably, this product boasts a huge 3” bypass valve that uses the factory NPP actuator, as well as a Siamese X-pipe with increased scavenging for maximum performance gains. The system retains all factory catalytic converters (some cutting is required).
Quality welds ensure strength, longevity, and good looks—especially in combination with the 4” twin-wall polished stainless tips with laser-etched Hooker logo. The 70501349-RHKR system uses factory mounting points to facilitate installation, while Hooker’s advanced tube geometry allows for straight-through performance and maximum ground clearance. All hardware is included.
