Just installed the M4 slip on exhaust. Like the sound a lot. Much deeper and louder then stock. Only problem is after I shift when I release the clutch there's some popping/backfiring sounds. Is this normal?

Yup, completely normal. It will only "pop" in the higher rev range. above 6-7K. You could tune it to get rid of it, but pretty much all slip on's will give you that.

Also just noticed where the new slip on pipe connects to the stock header there is some sort of leak coming out of the pipe. Hopefully this is normal as well...?

It's condensation, don't worry, it's perfectly normal. The backfire is caused by an influx of un burnt fuel and extra air reacting with each other in the pipe. Again normal. When your riding at night, there is even a little flame!

The reason you get the condensation is cause there is no gasket between the stock pipe and the pipe slip on joint. Only the flange sealant they provide. Mine only does it when it first starts up in the morning when it's cold out below 60 deg., once warm doesn't leak a drop.
