G morning ppl - i just wanted to add some additional stuff to this post. So, the other morning on my way to work, i decided to "gun" it getting on the highway; 2nd gear n half of 3rd pull. anyways, when i got to work, i noticed that the sound was just about completely gone which was a bit weird... then a couple of days later, the same thing happened. i floored the car in 3rd gear and when i came to a stop, the sound came back. it does sound to me like an exhaust leak.. Here is a video that i just took this AM - the sound quality is not the greatest. I will take another one in the afternoon and post
