It worked. My car sounded very hoarse so I installed a cheap double glazed window at a local shop as a sound box. It muffled the sound too much and I lost all the great sound that the VR6 makes. After reading it I bought it and it was perfect. Absorbs almost all of the rasp and has much better airflow than the cheap ones. The only complaint I have is that this muffler says on the Dynomax website that it has a 2.25" inlet/outlet. But the one I have is 2.5 inch. no big deal but not as described. (You need some back pressure on the motor to make it work/sound properly.) I'll post pics of the inside of the old double glazing and the bullet so you can see the bullets' obvious superiority.
