You have to contact DMC direct to get the retrofit kit.  Its $100 and comes with your choice of billet adapters, and they repack your mufflers for you.

Thanks. I called yesterday morning and they transfered me to someones voicemail. No call back yet.    The Office people knew what I wanted but were not sure what to do yet. They stated that they are trying to put up some info on the website.

Well I never got a call back but the info did finally go up on the website.
Power tune upgrade $94.95 + tax and outbound freight.  Kind of high IMHO since the exhaust is brand new. 

I am going to wait and see some dyno tuning runs comparing these.
