Reworked original engine sounds for Boxer Cup, both onboard and external.
Engine sounds have been low-pitched, and whine sounds have been turned down the volume a little bit in order to engine sounds to prevail. I believe the sounds are quite more similar to a proper Porsche 911 sound than the original Reiza one.
Update 1.1: added modified shifting sounds by @Randy Schulze . Now shifting sound are much subdued and can hear other sounds better now. Thanks to Randy!
Check out the new sound (obs: video made in v1.0. The engine sound didn't change tho, but the new shifting sound in v1.1 is not present in this video) (sorry for the watermark in video):
For comparison, check out the default sound:
Override all files in GameData\Sounds\BoxerCup. Make sure to backup first.
Important: No online mismatch.
