Tasteful exhaust note change

[m5james]

Hello all So I'm currently on my second X5, both of which I've simply deleted the resonator and installed an x-pipe in it's place, and while it helped a little, I'm looking for a little more. I did Magnaflow 14816's on my 740iL and it's about as close as I can get to sounding like the B&B Triflow that I heard on an E39 M5...no drone, none of that popping crap on deceleration, nice at idle and beefy under throttle.

https://www.youtube.com/watch?v=DvOsODR1pTY - this actually sounds nice and beefy, much like the $400 Magnaflows on my 740iL (my engine obsviously doesn't rev as fast but the note is a mirror image with mufflers only) without paying B&B's $1350 prices.

I've looked around for exhausts for X5's, but they're few and far between and/or extremely overpriced. I was doing Google searches for simple tip upgrades (I like the quad, I just want tips that completely fill the opening within the bumper) and came across these - BMW X5 (E53) DIESEL/PETROL STAINLESS STEEL EXHAUST BACK BOX TIP TAIL PIPE x2 | eBay Seeing this is a global forum, has anyone tried these on a 4.4i engine? If so, have you done anything else to the exhaust?
