Khian,
Create a custom box or get an existing one similar to ovb and obb and put all your neo items in there with script below for example:
rentitem 2548,300;
-this will make you use neo muffler for 5 minutes where 300 in (rentitem 2548,300; )is seconds

You might wanna do it manually though. Could be a lot easier to troubleshoot.

Ifaik i went way back to 14000s and compare the differences between the current and the past codes.
