You aren't limited to just using that one YouTube video I previously linked for reference, since there are plenty of other videos that you can watch and listen to. Sound tuning is one of the most complicated aspects of BeamNG modding in my opinion, so I can understand why getting the 5.0L Coyote sounds right can be a chore. And obviously, the exhausts found on export models are quieter than domestic ones due to various government regulations overseas.
Anyone interested can visit the following to learn more, either this one or that one. As a side note, Shelby models like the GT350 and GT500 have this system by default. The EcoBoost variant wouldn't receive it until a year later, but only when equipped with the quad-tip exhausts.
In 2018, GT models gain an active exhaust system when the dual-tip exhausts are swapped for the quad-tips. There is, however, a difference between the pre-facelift (2015 - 2017) and facelift (2018 - present) models that may affect the sounds. There aren't any differences between 20 models, as both are the facelift model years.
