Exported automation sounds sound better than vanilla sounds

I already posted this in the automation steam forum, but I want to present it to both dev teams simce there might be stuff that is more in tune with one game more than the other. Sometimes I decide to use an exported sound from automation on one of the vanilla vehicles. I replace the V8_cross_exhaust with whatever the sample name is. I am trying to figure out why the exported sounds sound better than the vanilla sounds (0.16) even though they are both from automation. Does it have to do with equalization or friction or something of that sort?

 

Can I get some help with this please?

 

Because its an old version...
