Default 2012 Outdoorsman CrewCab 4x4

Hey everyone. I am, for the most part, new to this site. I want some opinions as far as lift kits and exhaust systems. Saturday, if all goes well, I will be signing on a 2012 Outdoorsman (new) 4x4 with Hemi.
I have looked at a few different lift kits online. The one that stonds out to me the most is "Superlift Part Number K119B." I want to know if anyone knows much about them and quality of work. I am not wanting to lift a lot for a few reasons... One being I am kinda short, two being I only want enough to get to a few fishing holes nad some camping areas where more ground clearance is need. Also, with the lift and only 35s would it be necessary to upgrade the gearing? The dealership ordered the truck with 3.55 gears rather than the 3.92.
Next is the exhaust... I currently have a Flowmaster 40 Series Delta Flow with dual outs dumping before rear axle on my '08 Ram 1500 2wd. I like the way it sounds (cold air intake helps the sound too), but I am also wanting a little more aggressive. I have looked at MBRP, MagnaFlow, and few others. Any thoughts? I was also thinking of cutting the pipes after the Cats and then running it with an X-Pipe to two mufflers.
Any and all opinions and critisism are welcome. Thanks again, in advance, for your opinions and help guys.

I don't know about 3.55's with 35" tires from personal experience, but i think you won't get very good gas mileage with that. I have 3.92's with 35's and i get about 14-15mpg and this is with CAI and exhaust put on, but it still pulls real nice. I doubt you'd ever make your money back if you put on 4.10s gears or something though

Just using a quick calculation, Tire diameter X PI(3.14) divided by gear ratio equals distance travelled by said tire in 1 rotation of the drive shaft therfore

Stock 33 X 3.14 = 103.62 divided by 3.55 = 29.19 inches

35's 35 X3.14 = 109.90 divided by 3.92 = 28.04 inches

In my case, I have 37's, therefore

New 37 X 3.14 = 116.18 divided by 3.92 = 29.64 inches

From this I would conclude that for me by simply going to 3.92 gears, this would return my performance to pretty much stock, for a 35 inch tire, ever so slightly more pull.

I'm no engineer, but I would think going 4.10's or 4.56's would make the truck pull better, however, RPM is higher, and to me higher RPM = poor fuel economy

33's with 3.55 gears @ 1500 RPM will travel 3648.75 feet in 1 minute
33's with 4.10 gears would have to travel @ 1732.69 RPM to cover same distance
33's with 4.56' gears would have to travel @ 1966.10 RPM, if my math is correct thats 466 RPM faster, and IMHO that = more $$$ at the pumps, so yes, when you mash it off the line, you'll pull ahead, but at some point down the road, the 3.55's will catch you and still be pulling on the way by, again, I am not an engineer, I'm just using basic formulas we used when setting up our rear ends on race day, depending on the track we were at.

So, what I am gather from you two, is that with the 3.55 I should be good either way. I do understand that if I were to go bigger on the lift and tires I would most definitely need to redo the gears.

Nest things, did either of you catch what I had asked about the exhaust or the brand of lift kit?

I currently run BFG 37x12.50x17, my wheels have a -12 offset, and right now I only have a Ready Lift level kit, I will change out to probably 3.92 as I do a lot of highway driving, I hate driving down the highway with the engine wanting another gear, as in tow mode, you loose your OD, and in my opinion thats when these engines really start to drink
