What could be this sound?

Randomly hear at idle and sometimes at accelerate. The sound is intermittent at Left driver side. Exhaust leak? Sounds like paper being ripped

Recently afm delete and installed JBA headers.

Start by taking the belts off and see if the noise is still present, if not then start spinning pulleys by hand and see if you can narrow it down.
