JBA LT Headers, Cajun B Pipes, UpRev Tuning questions

Well, the '08 Mada is right on schedule. Pretty sure I got a cracked manifold. Just trying to confirm. Does it make a clicking noise when the motor fires? I believe that's what my issue is.

I am currently gathering all of the tools and assorted gaskets that go along with purchasing the Stage II performance kit from CajunBpipes.Com. I plan on going with catted b-pipes and keeping the factory exhaust to keep the increased sound to a minimum. Anybody got a sound clip of this particular setup?

Also, I am selling my BullyDog Triple Dog GT to help fund the purchase of the headers and bpipes. The stage II kit comes with UpRev tuning. Can someone please explain to me how the tuning works (i.e. what are datalogs? how do I apply the tuning? HOw do I send and receive tuning info? How many tunes do i get? etc)?

Hoping to order my Stage II kit in the next couple of weeks and will use the awesome "how-to" thread that was posted on here recently to accomplish the install. I have never undertaken this big of a task on the armada so I am rather nervous but can't see spending a bunch of money to have somebody else do it if i have the tools already.

I would appreciate any and all advice, answers to my questions above, and any other input.

Thanks!
