Corsa Axle-Back Exhaust System Dual Mode NPP Carbon Fiber Tips

The Corsa Axle-Back Exhaust System with Dual Mode NPP and Carbon Fiber Tips is a valved performance axle-back exhaust (also called a rear muffler section or axle-back kit). It lets you switch between a quieter cruising sound and an aggressive, full-volume exhaust note. Corsa builds it in the U.S.A. around its patented Reflective Sound Cancellation (RSC) technology.

Key Features:

• Dual Mode NPP valve: Plugs into the factory NPP module, so you can change the exhaust sound without losing performance. Corsa states that sound choice does not affect performance gains.
• Large sound range: Corsa reports a difference of over 12 dB between valve open and valve closed.
• Reflective Sound Cancellation (RSC): Patented technology that tunes an aggressive note under acceleration and reduces drone at cruise, whatever the valve position or mode.
• Improved flow: Corsa reports about 18 percent better flow than stock.
• 304 stainless steel construction: Resists corrosion and is built for long service life.
• Carbon fiber tips: Dual-wall exhaust tips with a carbon fiber finish for a premium look.
• Robust valve assembly: Corsa developed and tested the valve over an extended period under real-world conditions.
• Bolt-on installation: Printed instructions are included, and full-color instructions are available online.
• Warranty: Limited lifetime warranty on the exhaust, with 5-year coverage on the valves.

This axle-back system suits drivers who want a more aggressive exhaust sound, better flow and carbon fiber styling. It also keeps the factory-style valve control, so the sound stays easy to adjust.
