Corsa Xtreme 3.0" Axle-Back Exhaust with 4.5" Polished Tips (21077) - 2006-2013 Corvette C6 Z06/ZR1
Unleash a more aggressive exhaust note from your C6 Corvette with the Corsa Xtreme 3.0" Axle-Back Exhaust System. Designed for the 2006-2013 Corvette Z06 and 2009-2013 Corvette ZR1, the 21077 combines Corsa's aggressive Xtreme sound level with a freer-flowing exhaust design, measurable horsepower and torque gains, reduced weight, and polished 4.5" Pro-Series tips.
With gains of up to 15 horsepower and 16 lb-ft of torque, a 45% increase in exhaust flow, and 13.3 lbs of weight savings, this Corsa Axle-Back delivers more than just an exhaust sound upgrade. It is a performance-focused system built for two of the most capable models in the C6 Corvette lineup.
Xtreme Sound Level
The 21077 features Corsa's Xtreme sound level for Corvette owners looking for an aggressive exhaust character. Designed as the performance-oriented sound option, the Xtreme system gives the Z06 and ZR1 a stronger exhaust presence to complement the high-output V8 under the hood.
Up to 15 Horsepower and 16 LB-FT of Torque
Corsa rates the 21077 Axle-Back for gains of up to 15 horsepower and 16 lb-ft of torque. These performance gains make the system an excellent upgrade for C6 Z06 and ZR1 owners who want to improve exhaust performance while also transforming the sound and appearance of the car.
45% Increased Exhaust Flow
The Corsa Xtreme Axle-Back provides a 45% increase in exhaust flow. The freer-flowing design helps reduce exhaust restriction and supports the airflow demands of the high-performance LS7 7.0L V8 in the Z06 and supercharged 6.2L V8 in the ZR1.
The increased flow also makes the system a strong addition to Corvettes equipped with other performance upgrades where improved exhaust flow can help complement the rest of the combination.
13.3 LB Weight Savings
In addition to improving exhaust flow and performance, the Corsa 21077 reduces exhaust system weight by 13.3 lbs compared with the factory components it replaces. Removing unnecessary weight while improving airflow makes the system a functional performance upgrade as well as an acoustic and visual improvement.
3.0" Axle-Back Design
The 21077 uses a 3.0" Axle-Back configuration with a dual rear exit layout. By replacing the rear portion of the exhaust system, the Corsa Axle-Back provides a focused upgrade for owners looking to improve the Corvette's exhaust sound, performance, flow, weight, and rear appearance.
Twin 4.5" Polished Pro-Series Tips
The system is finished with twin 4.5" polished Pro-Series exhaust tips at the rear. The Pro-Series tips feature dual-wall construction and a slash-cut design, creating a substantial performance appearance that complements the aggressive character of the C6 Corvette Z06 and ZR1.
The polished finish provides a clean contrast at the rear of the Corvette while the large 4.5" outlets give the system a purposeful aftermarket appearance.
Built for the C6 Z06 and ZR1
The Corsa 21077 is designed for two of the highest-performance factory variants of the C6 Corvette. It fits the 2006-2013 Corvette Z06 equipped with the 7.0L V8 as well as the 2009-2013 Corvette ZR1 equipped with the 6.2L V8.
Whether upgrading an LS7-powered Z06 or a supercharged ZR1, the Corsa Xtreme Axle-Back delivers an aggressive sound profile together with documented improvements in horsepower, torque, exhaust flow, and weight.
