I don't know exactly what that's a link of but that's not a TSX anything on that car. The TSX is really defined by it's headlights which bend completely the other direction from the Accord. Also the TSX front fender is defined by it's concave and convex bend at the midline, the 6th gen Accord has none of this. The 7th does to some degree.
If you want to put some odd bizarre bumper on your Accord and call it a TSX front end far be it from me to question that call. But a TSX nose is defined by having TSX parts? I fail to see how either car has a TSX front end, hell neither even has a TSX grille? And both still use an Accord hood, fenders, and headlights. So you have a 6th gen with a unique bumper, how the hell is that a TSX conversion?

Accord 6th gen...

TSX...

up close -- fender contours, hood with flat leading edge, and headlights that would never fit an Accord.
