New to Forum and Need Help w/ my Civic

Hey all, I'm new to the forum and also new to cars as well. I dont really know much, but I do read lots of magazine about cars modicifations. I have a question about my 95 Honda Civic LX 4D. I just recently bought a second-hand Millenium Style Double Tip from a friend. I was wondering if it good to install it into my car? Does it worth it? or Do All of you think that I need to get a new muffler? Any suggestions will be highly appreciated. Thank you all
