NAP QUAD flap exhaust system for the Corvette C8 Stingray

Features

• A matching rear diffuser is supplied. This is specially designed for our exhaust system. Optionally available in black-painted or in carbon. Our diffuser can be fitted and removed without modification to the vehicle.
• The two electronic Highspeed 3″ NAP flaps only need a few milliseconds to open and close.
• The flaps are electronically damped, which prevents material fatigue and leaking hard stops.
• The flap control behaves completely passively. No intervention in the original Corvette CAN control is necessary. Reversion to the original condition is possible without manipulation of the vehicle software. This allows the manufacturer's warranty to be retained.
• Switching of the flap modes via the Z-mode button (equipment-dependent) or separately via the NAP button.
• Thermal insulation that prevents heat damage to your Corvette Stingray.
• Production serial number engraved on the silencer.
• The system emphasises the powerful expression of your Chevrolet Corvette Stingray C8 with the appropriate sound. In addition, the power and torque are increased
• NAP Automatic Wireless Valve Control

The flap exhaust is controlled by the NAP Automatic Wireless Valve Control. The NAP Valve Control electronic control unit is the brain of our flap exhaust systems. Because the NAP Valve Control unit can read Canbus signals coming from the engine's ECU, it ensures that you are always driving in compliance with the law, no matter what mode you are in. The system is bound by the parameters set by the EU. If necessary, it intervenes smoothly and seamlessly. The electronic flaps are switched from sporty comfort to a throaty racing sound via the NAP button in the cockpit.

The NAP Automatic Wireless Valve Control is based on an interference- and tamper-proof connection between the NAP CAN-BUS radio dongle and the flap control. We have reduced the hardware of the valve control to minimal dimensions. The control unit including the radio module is hardly thicker than a cable.

This results in much simpler installation: the cumbersome laying of cables through the entire vehicle is now a thing of the past!

In addition, our NAP CAN-BUS radio dongle can be looped through, i.e. you can connect other devices to the CAN-BUS and operate them without interference.

TÜV information

There is a generally valid ABE for Germany and an EC approval number for the EU. The number is engraved on the system and you will also receive a written copy of the certificate. With the exception of a few countries, the ABE is even valid worldwide. Our sport flap exhaust system is registration-free.
