I'm wanting to pull the fuse/s on the NPP in my 19 ZR1. Does anyone know for sure what the correct fuse number/s are. The OM shows 1 fuse for the right side and 1 fuse for the left. I know on my 16 Z06 it's number 42 and that opens both valves on it, but the ZR1 looks different. I know that they can be set in settings, but I don't like them closing under certain conditions.
Thanks for your help.

If I’m not mistaken you can go into the settings and select track mode on the exhaust and it should stay there no matter how you drive.

NPP Fuse #41 (2014), #42 (2015 - 2018), #87 (2019).

The fuse is in the same physical location, but fuses have been renumbered over the years. Check the online manuals for exhaust valve 2.

No, they still close unde part throttle at certain speeds. That's why I said that in the original post.

They close somewhat under certain conditions to meet the Federal drive by noise standard even when set to track.

Yes, exactly.

I used the M2W switch wired in the fuse box under the hood it's not to hard to do.

You will re-use the 10 Amp fuse #42 you pull out so keep it close. Then you can control loud or quiet with the fob. Quiet in the neighborhood, loud on the street.
