D&D vs Jardine exhaust, and what to do about my ECM

[getsch]

Hello, Ive got a 2005 Buell XB12R with a Jardine carbon fiber on it right now. Ive been wanting to tweek the bike a little more and was wondering what exhausts are really worth the money especially over what I already have. I heard D&D's are nice and one of the loudest, which I like.
I also have a question about the ECM. I'm not sure how adaptable the stock ECM is and what I should do to peak the performance either with my stock jardine or with another pipe if i decide to go with it. The previouse. Ive seen the race ECM and thought of going with that, the only question I have is how do I go about mapping it and what kind of gains would I be looking at?

In case you've not found it yet: Huge Exhuast Thread (http://www.buellxb.com/Buell-XB-Forum/General-Motorcycle-Chat/the-big-buell-exhausts-topic)

Also, you're ECM is re-programmable with the ECMSpy software. You can essentially turn it into a Race ECM, which would save you major bucks.

Here's the ECMSpy download: ECMSpy (http://www.buellxb.com/Buell-XB-Forum/Do-It-Yourself-Buell-Mods/ECM-Spy-Download). You'll also need a cable to connect to the ECM - get it from Xoptiinside.com, Ebay, or someone off this forum.
