Well guys, I've just taken ownership of my brand spankin new 2007 GXP. I absolutely love it, but I got to get a more throaty exhaust. Anybody on the board changed their exhaust system or perhaps just the mufflers ?

Welcome. I just bought mine about 3 months ago and I love it too. What seems to be the popular and inexpensive thing to do is have the resonator cut out and replaced with a straight pipe. I had it done at Mieneke a month ago for 60 dollars. Made a big difference and is ALOT cheaper than getting new mufflers.

I would go with cutting out the resonator myself too.
Let me know if anyone comes up with the best way to lower a GXP.
