Yes, there is a smell.
It’s loud. I would say double.
Way more pops and burbles. They sound like gunshots.
You can hear the turbos spool a lot louder.
You get a check engine light, but my car is tuned so it took care of the light.
All in all, I highly recommend it. As for the smell, you will not smell it as much but only if ur in sport plus and just idling you definitely will. Check out my Instagram for a sound clip. @ orange_m340i
