I just traded in my '96 V6 stang for a new (for me) '02 GT. I absolutly love the car...day and night compared to the Sixer. Here is the deal, I want to put a cat-back system on the car and I am very picky about sound. I want something that is close to the same volume level as stock and highway cruising speed but when jumped on will scream. Any suggestions? Thanx.
