Corsa 14777 Axle-Back Exhaust System with Dual Mode NPP

The Corsa Performance 14777 Axle-Back Exhaust System features Dual Mode NPP (Noise Preference Program) technology, allowing you to switch between a refined touring sound and an aggressive sport exhaust note at the touch of a button. This complete axle-back system is engineered to replace your factory exhaust from the rear axle to the bumper.

Patented RSC Technology:

Corsa's Reflective Sound Cancellation (RSC) Technology eliminates drone frequencies inside the cabin during cruise, delivering a comfortable daily driving experience while unleashing an aggressive exhaust tone under acceleration. This patented design uses precisely engineered internal cores to cancel out unwanted sound waves without restricting exhaust flow.

Key Features:

• Dual Mode NPP valves for switchable exhaust sound profiles
• 100% drone-free experience during highway cruising
• Aggressive sound under acceleration and wide-open throttle
• Direct bolt-on installation with factory mounting locations
• Premium stainless steel construction for corrosion resistance
• Performance gains across the RPM range without sacrificing sound quality
• Integrates with factory NPP controls and drive mode selections

This system is precision-manufactured in the USA and includes all necessary hardware for installation. The mandrel-bent tubing ensures maximum exhaust flow for improved horsepower and torque, while the polished stainless steel tips deliver a premium appearance.
