I have the Dinan exhaust, tune and intake. I think it is just enough...slightly louder and more burbles. Does not give the pops unless you are upshifting at high rpm in low gear. I kind of wish it did upon deceleration too. Oh well. It is a very nice compromise. I did it all at once so not sure which added the power but it woke it up nicely. The X5M is my absolute favorite daily driver. IMO much better than the 2 previous Cayenne turbos that I had.
