Cicio Performance Corvette C8 Exhaust Module


Cicio Performance Corvette C8 Exhaust Module

(1 customer review)




After installing several aftermarket exhaust systems on various C8’s, we quickly discovered that even though a lot of the systems on the market have the valve actuator brackets for the main valves when the car goes from 4cyl to 8cyl operation, that there is still a check engine light that appears.


We realized that this eye sore would not be preferable to 99% of the owners out there so we set out to figure out a solution for this.


Our exhaust module is a direct plug in item with very simple installation and will eliminate any check engine lights caused by the valve system on the factory exhaust!

    Corsa says you can delete the NPP valves without throwing a check engine light…..Not true for the 2021 C8. It will throw a CEL every time it does not see the NPP valves.  I have a dear friend that works for a Chevy dealer that has the scanner/software to get into the C8. He did a relearn on the AFM valves and it still threw a CEL after we unplugged the NPP valves.
      The solution was Cicio Performance Corvette C8 Exhaust Modules! I bought the AFM and the NPP delete modules, plugged these in, and no CEL! I been driving around on these for about 500 miles and so for so good. If you are going to change your exhaust and delete your NPP/AFM valves this is for you. I was treated very well by the people at Cicio, and got them right away. I have a friend that ordered an exhaust for his C8 and I ordered a set for him too.
