All the magazine db measurements that they test for vehicles is done on the inside of the car. The purpose of the test is to see how quiet the car is, not how loud the exhaust is. It shows how much tire, wind, road and yes exhaust noise makes it into a car. Poor insulation, aerodynamics etc. can give you a high interior db reading as well.
