M Performance exhaust question

So I'm kind of a newbie here, but I have a question for anyone that can answer it. I realize that some of the exhaust sound is "piped in" to the cabin, with the car setup with the stock exhaust. What does that mean for the M Performance exhaust? Is that also piped into the cabin, but much louder? Or is that feature a fixed and unchangeable variable on how the exhaust sounds inside of the car? Or is that feature deactivated somehow since the performance exhaust is so much louder that it would overwhelm the interior of the car??

Just trying to figure out if the M performance exhaust, as nice as it may sound on the outside, is going to ruin sound, radio, conversation, etc on the inside of the car.

Thank you.
