hey man since they are discontinued you could look into the Steeda Cat-back. i know its not the same but i have it on my gt and my best friend has it on his 03 cobra and it sounds amazing. its kinda like what that guy stated before its quiet at idle but when you get on it... it screams. here is a vid of my car and ill post a vid on his 03 up here tomorrow or this weekend just depends on how busy i am.
