Anyone ever done exhaust cutouts or varex mufflers?

thinking about doing a exhaust setup where I can switch between stock silent and race loud with the push of a button. the two options I have found so far are simply exhaust cutouts, or there is a company making a variable muffler system called varex that would do the job without having to dump the exhaust under the car. I've ran through the different scenarios in my head a few times and realized id probably just want to do a mid muffler delete, and install two varex mufflers to replace the stock ones. any thoughts, guidance or ideas of how i could achieve the ability to turn a loud exhaust off and on.
