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?

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!
Good morning, and in case I don't see ya, good afternoon, good evening, and good night!
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.
