My exhaust actually got quieter for me, inside the car, but it is just as loud, if not a tad louder outside the car. So not always going to be the same for everyone, cababah said his added more for the driver to hear, and for me, it took away sound.
I have the ford racing sport (same as Borla s) mufflers and restrictor plates removed for the boss side pipes.

The mufflers were installed first and the cabin was still fairly quiet but when I added the side exhaust, cabin volume went up a lot and I got a small drone at 2k rpm.
