I have the BMW PE without the Y-Pipe resonator delete installed presently on my N54. It does sound good, deep down low and a very high pitched/high performing 6cyl sound up high. I love it but it's by no means massive over stock, a better tone for sure though. It'll be louder with an N55 as you have three less Cats. I plan to install N55 mids and the Y-pipe, that should then make the N54 sound good; then it's DP's and off with the N55 mids as I'll most likely go deaf with that combo.
