Corsa Xtreme Axle Back Exhaust Corvette C6 Z06 / ZR1 (2006-2013)

Give your C6 Corvette Z06 or ZR1 the aggressive exhaust note its high-performance V8 deserves with the CORSA Xtreme 3.0" Axle-Back Exhaust System. Designed specifically for the LS7-powered Z06 and supercharged LS9-powered ZR1, this system combines CORSA's most aggressive Xtreme sound level with its signature drone-canceling technology for a dramatic improvement in sound without sacrificing highway comfort.

The system features large 3.0-inch exhaust tubing and quad 4.5-inch dual-wall Pro-Series tips, available in your choice of Polished Stainless Steel or Black PVD. CORSA's Reflective Sound Cancellation® (RSC®) technology is engineered to target unwanted frequencies inside the cabin while allowing the LS7 or LS9 to deliver an aggressive exhaust note during cold starts, acceleration, and high-RPM driving.

CORSA reports gains of up to 15 horsepower and 16 lb-ft of torque, a 45% increase in exhaust flow, and approximately 13.3 lbs of weight savings compared with the factory exhaust.

Product Features

• CORSA Xtreme Sound – CORSA's most aggressive sound level unleashes substantially more of the LS7 or LS9's natural exhaust character, especially during cold starts and wide-open throttle.

• RSC® Drone-Canceling Technology – CORSA's Reflective Sound Cancellation technology is engineered to control the frequencies responsible for unwanted cabin resonance, giving you aggressive exterior sound without the constant highway drone associated with many loud exhaust systems.

• 3.0-Inch High-Flow Design – Large-diameter exhaust tubing provides the flow capacity appropriate for the high-output Z06 and supercharged ZR1 platforms.

• Up to +15 HP & +16 LB-FT – CORSA reports measurable horsepower and torque gains from the freer-flowing design, although actual results can vary by vehicle and modifications.

• 45% Increased Exhaust Flow – The performance-oriented axle-back significantly improves exhaust flow compared with the factory system.

• Polished or Black PVD Tips – Choose Polished Stainless Steel for the classic Corvette center-exit appearance or Black PVD for a darker, more aggressive finish. CORSA describes its PVD coating as a vacuum-deposited finish designed to resist chipping, flaking, peeling, and corrosion.

Why Upgrade?

The C6 Z06 and ZR1 represent two of the most exciting performance cars of the C6 generation, and both deserve an exhaust system that lets their engines be heard.

On the Z06, the CORSA Xtreme brings out the raw character of the 7.0L naturally aspirated LS7, giving the car a much more aggressive presence as the engine climbs through the RPM range. On the ZR1, it allows the supercharged 6.2L LS9 to deliver a deeper and more authoritative exhaust note that better matches the car's performance.

Unlike a basic muffler delete or straight-through exhaust that simply increases volume, CORSA engineers the Xtreme system around controlling unwanted cabin frequencies. This makes it particularly appealing for a street-driven Z06 or ZR1 where you want serious volume when you're on the throttle without living with excessive drone every time you cruise on the highway.

Finish the system with Polished Stainless Steel tips for a clean, traditional look or choose Black PVD tips for a stealthier appearance that pairs especially well with black wheels, carbon fiber, and darker exterior accents.

Give your C6 Z06 or ZR1 the sound it should have had from the factory with CORSA Xtreme—3.0-inch performance exhaust, massive 4.5-inch tips, and your choice of polished or Black PVD finish.
