I am looking to upgrade my cat back system on my 99 cobra. I do not want to spend an arm and a leg to get something. I know everybody and there brother asks this but what kinda system woudl you go with? Is there a website where i can go and hear what it woudl sound like on my car? I know there was one a while back. I am in the under 400 range for a cat back system. I have been looking on e-bay but i wanted to get some input from you guys.
