Murano Upgrades????

This is to the people that have done upgrades to their Murano. What is the single best bang for the buck upgrade you have done to your Murano? Cold air? Exhaust? Power programmer(if they even make it yet)? And Non-performance wise too. Like new speakers?, Tint? Navigation? New paint job?

Just trying to start up some conversation it's been pretty slow lately.

Thanks

And one year later it still is very slow

Yep almost a year after that still slow. Am I the only one on this forum???
