Retaining sounds from the OE

I have downloaded and tried a few of the different carset mods on here. My hat's off to some of the great work which are very good, such as the F1 1993 and 2002, not to mention some of the great work offered for sportscars and indycars. I still prefer the sounds from the OEM game that came with GP4. Is there a way to utilize the OEM sound files when running the different car mods?

Thanks sincerely,
