Hmmm i don't know about the backpressure side of things, the folks on tdiclub seem to be of the impression that the turbo itself provides back pressure - how correct that is i don't know as i'm no mechanic. I ended up fitting a small powerflow silencer in place of the OEM backbox after a week as it was just too noisy.
Like you i've NO complaints about the sound(s)
I too have heard that the turbo inselfs creates enough back pressure, but also heard it wouldnt, so rather than finding out the hard way, I figure keep the cat
