Exhaust crackle after installed rv6 catted downpipe

[Beach civic si]

Just installed the rv6 catted downpipe, and have noticed some exhausts crackles during some idle and deceleration
What does this mean? Does it signify car is running too lean or rich? is it bad for the engine?

I'm not an engineer so I don't know exactly what that means, but I know as long as its not a constant sound and it's not happening all the time then its fine. It's certainly not bad for the engine.

Any codes when installed

It's normal.

Crackles/pops is unburnt fuel that is being burnt in the exhaust and you are hearing it ignite in the exhaust pipes. Which is normal when you let off the throttle, especially during hard accelerations
