Those are very similar to the one's I have, I like 'em and all but I just don't like how the inner wall is so visible, making the inner part of the tip smaller, if that makes any sense. I've been peeping out what tips I'd replace them with and so far the winner is the tips that are on the new G35's, same shape as mine but possibly a little bigger and no reduction of the inner wall, they look just like regular single wall tips but with a rolled edge, oval shaped and angle cut. Now I wonder how much they'd cost me.
