Product Description


 

Transform the sound and appearance of your C6 Corvette Z06 or ZR1 with the Kooks Shotgun Valved Axle-Back Exhaust System. Engineered for the naturally aspirated 7.0L LS7 and supercharged 6.2L LS9 engines, this premium exhaust delivers an aggressive V8 exhaust note while incorporating integrated exhaust valves for additional sound control.

Manufactured in the USA from 304 stainless steel, the Kooks Shotgun axle-back features 3-inch exhaust tubing designed to improve exhaust flow and complement the performance characteristics of the C6 Corvette.

The system is finished with quad carbon fiber exhaust tips, giving the rear of the Corvette a distinctive motorsport-inspired appearance.

Designed to connect directly to the factory exhaust mid-section or a compatible Kooks Headers & X-Pipe system, this axle-back is an excellent standalone exhaust upgrade or finishing component for a complete Kooks exhaust package.

Why Upgrade?

The C6 Corvette Z06 and ZR1 are two of the most iconic performance Corvettes ever produced, featuring the high-revving 7.0L LS7 and supercharged 6.2L LS9 engines.

While both vehicles offer impressive factory performance, an aftermarket axle-back exhaust provides an opportunity to enhance their sound, appearance, and exhaust flow characteristics.

The Kooks Shotgun Valved Axle-Back Exhaust is engineered to deliver a more aggressive exhaust character while retaining the flexibility of an integrated valved design.

Unlike a conventional fixed-flow axle-back, the Shotgun system incorporates exhaust valves that alter the exhaust path depending on valve position. This provides greater flexibility in exhaust sound compared with a permanently open system.

The 3-inch 304 stainless steel construction provides a durable, high-flow exhaust design that works well with the factory exhaust mid-section or as part of a more comprehensive performance package.

For owners planning to install Kooks long-tube headers and an X-pipe, the Shotgun axle-back provides a matching rear exhaust solution designed to complement those upgrades.

The quad carbon fiber tips complete the system with a premium appearance, making the exhaust a visual upgrade as well as an acoustic one.

Whether you're looking to enhance the naturally aspirated sound of the LS7 or bring out the aggressive character of the supercharged LS9, the Kooks Shotgun system delivers a premium exhaust upgrade engineered specifically for the C6 Corvette platform.

Upgrade your C6 Corvette Z06 or ZR1 with the Kooks Shotgun Valved Axle-Back Exhaust—featuring 3-inch stainless steel construction, integrated exhaust valves, and quad carbon fiber tips for an aggressive combination of sound, performance, and appearance.
