It's like most things, personal choice is what is really all that matters, what one loves another may not so all that really matters is that you like it.👍
It's not one of my favourite aftermarket bumpers to be honest, well it's all fine except for the front foglamp air intakes, they just don't suit the B7 styling, just to square, better suited to B8 platform and beyond.
There are a few RS4 B7 aftermarket bumpers on the market and most tend to be very similar as yours and i know a few guys that have the same item fitted to their B7's, but there are a couple of companies that make an almost exact RS4 B7 front bumper but for the A4/S4 variants, so the wheel arch profiles fit properly, the oem rs4 B7 has wider arches so bumper won't fit.
The splitter you have fitted looks very similar in design as the lower lip as fitted to the B7 DTM which has a nice front bumper .
