The popping was always there but you start to hear it with a louder exhaust. Its harmless but some guys don't like it..... Some do.
As long as the popping isn't Backfiring.Where too low an
Octane is used.
Because incorrect mapping for aftermarket exhaust can cause
strange sounds like backfiring or popping.
Running lean would cause it.
Running rich would probably cause the engine to stall or
not turn over.

I heard that Honda was considering adding a couple
extra pages to their 128 pg. Honda Owners manuel.
On What makes your Honda Tick.
But the engineers decided agin it.
They weren't about to give away any trade secrets.
Since every model is so precious.Like a newborn baby is what.
