Doesn't look bad, but as others have said, you shouldn't be able to see the can once the diffuser is on. If nothing can be done, I'd paint everything black to mask it better. This is what I did with my Inside Performance quad setup, and you can't see anything.
I wouldn't get it simply because it sticks the pipes too far out to the sides like the 1M. I like the pipes closer to the center of the car, like the E46M3 and Z4M etc. Just personal preference!
