I've had turbo cars most of my life and this is the first time not being able to hear a pronounced whining/ whistle with a dp. Was thinking to just swap in the s63 turbos and call it a day.

could be resonators ? never had issue with hearing catless turbo cars, did you ever get a chance to snap pictures of the custom brackets ? wanted to see what solution was used.

They had it off the lift so going to be impossible to take pics unfortunately.
