Corsa Xtreme 3.0" Axle-Back Exhaust with 4.5" Black Tips (21077BLK) - 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 21077BLK combines Corsa's aggressive Xtreme sound level with increased exhaust flow, measurable horsepower and torque gains, reduced weight, and black 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 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 21077BLK features Corsa's Xtreme sound level for Corvette owners looking for an aggressive exhaust character. The Xtreme configuration gives the Z06 and ZR1 a stronger performance exhaust presence designed to complement the high-output V8 powering each application.
Whether paired with the naturally aspirated 7.0L V8 in the Z06 or the supercharged 6.2L V8 in the ZR1, the Xtreme Axle-Back provides an exhaust upgrade appropriate for the performance-focused character of the C6 platform.
Up to 15 Horsepower and 16 LB-FT of Torque
Corsa rates this Axle-Back system for gains of up to 15 horsepower and 16 lb-ft of torque. These documented performance improvements make the system an excellent choice for C6 Z06 and ZR1 owners who want an exhaust upgrade that provides measurable performance benefits in addition to a more aggressive sound and appearance.
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 7.0L V8 in the Z06 and supercharged 6.2L V8 in the ZR1.
With substantially increased flow compared with the stock exhaust components, the Corsa system can also complement additional performance modifications where improved exhaust flow is beneficial.
13.3 LB Weight Savings
In addition to improving exhaust flow and performance, the Corsa 21077BLK provides a 13.3 lb weight savings compared with the factory components it replaces. Reducing exhaust system weight while simultaneously increasing flow makes this Axle-Back a functional performance upgrade as well as an acoustic and visual improvement.
3.0" Axle-Back Design
The 21077BLK 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 their Corvette's exhaust sound, horsepower, torque, flow, weight, and rear appearance.
Twin 4.5" Black Pro-Series Tips
The 21077BLK is finished with twin 4.5" black Pro-Series exhaust tips. The Pro-Series tips feature dual-wall construction and a slash-cut design, creating a substantial performance appearance at the rear of the C6 Corvette.
The black finish provides a darker alternative to the polished-tip configuration and pairs especially well with the aggressive character of the Xtreme exhaust system. This 21077BLK configuration specifically features black tips despite the shared manufacturer description referencing the polished-tip version.
Built for the C6 Z06 and ZR1
The Corsa 21077BLK 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 a Z06 or ZR1, the Corsa Xtreme Axle-Back combines an aggressive sound profile with documented improvements in horsepower, torque, exhaust flow, and weight, along with black Pro-Series tips for a more aggressive finished appearance.
