VIDEO: Holley BlackHeart Announces a 304SS Cat-Back Exhaust System For C8 Corvette

Our friends at Holley have announced a stainless steel cutback exhaust for 2020-21 Corvette C8. Constructed from 304 stainless with NPP Dual Mode and AFM Valve Simulators and a quality design. As powerful as the LT2 is, there’s always room for improvement.

Official Release:

2020 C8 Corvette 6.2L, 3 in. to 2.5 in. 304SS Cat-Back Exhaust System with NPP Dual Mode and AFM Valve Simulators

This Hooker BlackHeart 304 stainless steel Cat-Back exhaust system will make your 2020 C8 Corvette sound like the supercar it is. The polished high-flow straight through muffler design will not only give your car a deep aggressive rumble, but it will also reduce the weight of the exhaust system by 19 lbs. The muffler also has an internal X-Pipe design to act as a balance point between the two cylinder banks, improving performance. This helps keep the in-cab sound level very moderate at cruising speeds, allowing you to better enjoy the experience of driving the car.

Also included in this system are exhaust valves and simulators that reuse the factory valve actuators to give you the open exhaust performance and sound when you need it. The system includes mandrel bent 3-inch tubing to maximize the exhaust flow, along with 2.5-inch tubing through the muffler and is finished off with four 4-inch double walled polished stainless steel tips that have the Hooker BlackHeart logo laser etched into them for great looks. This exhaust system includes hardware and utilizes the factory mounting points for a hassle free installation. Backed by Hooker BlackHeart’s limited lifetime warranty.
