I want to make my exhaust a bit louder on my 435xi m sport. I already have a catless down pipe, but still looking for more. I was thinking of doing a straight muffler delete, but I'm worried that would be too loud. My local muffler shop suggested doing an electronic exhaust cutout. What do you guys think? This way it could be loud when I want, and quiet when I want.

Could it cause any problems due to loss of back pressure, etc.?

Any other suggestions appreciated. Thanks!
