Replace the muffler and have the resonator deleted. Don't forget to transfer the rubber piece and plug the vacuum hose that controls the valve on the old muffler. The pipes are the same size.
When I had mine done, my exhaust guy looked at the new PE and said, "Looks like the same thing to me". He asked if I just wanted to delete the resonator and unplug the vacuum hose. I opted to have the PE installed as I it was already paid for and sitting in his shop. There is a ton of videos and stuff out there on resonator delete. I don't know how much different the mufflers actually are. They do look the same, except for the tips. I drive an 06 330i. Hope this helps.
