When I put my finger over the hole (on a cold start of course) I can feel that the air coming out of the hole is constant with the popping noise. Could this hole be making this noise, if not what could possibly be the problem? It's not the valves nor the throttle bodies because I just had it serviced and they didn't mention anything about the noise. Thanks

A broken hole in the exhaust system, or any other kind of exhaust system leak, will definitely cause popping sound in this bike - particularly during deceleration. Seal it up and it may go away.
They may have not mentioned anything about the noise because a lot of Triumphs do pop on decel after a few tuning adjustments, largely due to needed tweaks in the FI mapping.

Is the hole on the bottom, perfectly round and machined (smooth) like it was put there by the manufacturer?
That's a drain hole to let water drain out to prevent the exhaust from rusting from the inside out.
If it's a rusted through hole, or definitely made by damage, the hole should be repaired.
That would be causing the popping.
Buy a new exhaust
Get the hole welded shut
Seal it with "muffler tape" (available at auto parts stores).
Muffler tape, melts when it gets hot and conforms to the hole, then dries hard as a rock.

Popping or backfiring is many times an illustration the gas air combination is off. using fact it stopped, sounds like that's the place it ought to be. in the journey that your bike makes use of closed loop gas injection, the laptop would have finally gotten the combination found out.

The idea for a drain hole came from the manufacturers that used them. This one doesn't really sound like a drain, though.
The hole can be welded or patched.
