Need more doof!!!
The Merc driver also has a few other things going for him:
Its quiet inside
He doesn't have ICE, he has a surround sound hi fidelity integrated entertainment system
He can't here the motor
He can't hear road noise
There is no vibration
He has no squeaks or rattles
And did I mention....its quiet inside
If you get a quiet exhaust system, you will still have all the above..........but now you will be able to hear it!!!
