I think that I am going to get a top gun undertail to clean up the look of the rear of the Busa. I was just wondering how hard they are to install. I was looking at the installation on alliedbarter.com and I see that it requires some cutting. I don't want to try and do it my self and mess up the rear if I cut it wrong and totally mess it up. I'm thinking that I can do it, I just want to see what other people have to say about installing it. Thanks.
