Anyone ever try exhaust cutouts?

I have the electric ones on my 2012 Challenger and I love them! I've had them for about 4 years now. You need to check your state laws because they are illegal in some states.
You can go from full muffler to open headers and anywhere in between with a press of a toggle switch.
That being said, keep in mind that they sound good FROM INSIDE THE CAR. They may NOT sound good from the outside, so if you are trying to impress people with a classic loud muffler tone, you may want to go a different direction. On the other hand if you are like me and don't care what others think, they may be just the thing for you.
