It's subjective, but I assure you the MPE sounds way better than the MPE on a M4.

A few considerations, are you sure you have a MPE? Can you take a picture of the exhaust canister? Sounds crazy, but some people are confused about what comes on a competition package car. The MPE is not standard on a competition car.

Here is a picture:

Also, your car may have ASD unplugged or coded out. And your M4 may have had ASD on. At least check this as well. I remember when I unplugged my ASD, The immediate reaction was the car's interior cabin was quieter and less boomy.

However I could hear my exhaust pop. It only happens in certain situations, hard to duplicate all the time. I can tell you, I definitely can hear my exhaust. Windows down it just sounds amazing.
