Hey guys! I was wondering if you'd be able to identify this noise, now keep in mind I have a different intake and exhaust. https://photos.app.goo.gl/Rtd1izLGoAH6n3PLA
Now yesterday everything sounded pretty normal, but today it's a bit quieter and doesn't have the loud resonance-y noise around 3750rpm instead it sounds a bit more stock, I mean it is a bit warmer outside and im sick but what is that odd squeaky/chirpy sound?
