[B:M:W]

I have a F30 with a N55 engine. I put a valvetronic axle-back valved exhaust on the car which created the sound I wanted but it is still quieter than I want.

To increase the volume, I am thinking about either adding a catless downpipe or doing a resonator delete but I am curious to hear other people's experience and if there are any other solutions before doing so.
