I have a 1994 GT and recently put an X-Pipe and Magna Flow exhaust. I am very disappointed in that there was virtually no sound difference. It still has the factory cats. Some tell me that that is the reason others say taking off the cats will make no difference that its the mufflers. Can someone please clarify this for me?

 

this has nothing to do with forum suggestions or feed back for the forums. This should be in general tech.
