Thanks for the additional info...I'm on Trail Duty's site now.

As for installation...I've had my local dealer to all my work so far. They're kind of a niche dealer, they're all Corvettes, Hummers, and GMC trucks. They did the install for everything in my first post (minus the CIA, plus an oil change) for $1,600...and that included some custom work on the Flowmaster to keep it up under the truck like the stock pipes.

I hate to sidetrack my own post...BUT, after doing some more reading on the forum I find myself torn between 4.88s and 4.56s. I ordered the Superchips Cortex 2950 to reprogram the truck for the tire change and as a prep for the gear change, but I'm thinking that maybe the 4.56s would be a better pick for me.

I'll do some more research and perhaps open another thread once I can better articulate my questions/reasoning.

Thanks, Orange, for the Trail Duty link.
