Here is a list of exhausts you can order with a quad tip. Personally I like the sound of quad tips, and yes I understand it's purely subjective. If anything they add weight. Not enough weight to scare me off, though.
I searched quite a bit and couldn't find many, please post others so we can add to this list. (I'll update this and post better links when I have time). For best effect, just google their title.
