Default Exhaust code on build sheet

Hey Guys,

I am pretty sure the code for NPP is NPP. But what is there if the car does not have NPP?

Also, if I get a car without NPP is it possible to put a switch on the car that basically acts like NPP? For example, the Mild-to-Wild controller.
I am assuming the base vette without NPP sound like the cars with NPP and the valves are closed.

Thanks.

Do does that mean if it doesn't have NPP it's just not there or is something else listed?

I don't have answers to all your questions, but if you're trying to determine if your car is equipped with the Performance Exhaust, you can also look in the battery area for the "Service Parts Identification" sticker and see if "NPP" is listed.
