I have recorded a great sounding Ferrari Challenge Stradale with Capristo exhaust. You can hear the valves get open and closed. After a couple of huge revs you can hear a fly by sound with the valves open!I hope you like the sound and feel free to leave a comment behind!Thank you guys for all the support you do on my channel.
