I'd love to hear some videos, Cattivo. The only one I've heard from an actual X5M is the black one I linked above, otherwise everything else has been on M5's.
Can I ask why you did the H-pipe and can bigger tips be installed? The biggest tips I've found online are 4" or a little over 8" combined, but I was curious about fitting larger...assuming I can even find them.
I've seen those Akropovic tips, but at $420 a pair, that's a bit steep. I've been looking at mostly black or that burned titanium look to match the vinyl CF wrap I'm going to do to minimize how obvious the hitch looks.
