When I had my car I had a bolt-on chrome tip. I got it online for like $10 or something like that. The stock tip is a 2 inch. I think mine was maybe a 3 inch. It tucked up there nice and you couldn't see the bolts.
Not a great photo, but maybe it will help.
I put one on my truck, but I need another one. The one I have is not long enough and you can easily see the bolts, etc. Not great. But for now, better looking than a rusty tailpipe.
