Dinan Exhaust or Software Boost

I just got my 550i and have been looking into getting the dinan upgrade. I plan on getting either the exhaust or the S2 software upgrade. If I get one I'm not sure when I will get the next, if ever. If you guys were to choose, which one would you recommend? Any experience with either?

Mein Auto:
I'm in the same boat. In fact, I've made a spreadsheet of my planned mods and costs. I'm planning on the Dinan S2 tuner first, because I think it will make the biggest difference in daily driving. After that I will be moving on to springs. I'm not convinced yet I want to do an exhaust (I kind of like the car quiet with a non-modded appearance), but if I do, that will be third.

Definitely the stage 2 software first. The Dinan exhaust is a little disappointing when it comes to sound.

I'm thinking about the Dinan springs and Shockware software.. I'm with sunibalt regarding the exhaust. For your question I'd go with the S2 tuner.
