Bigger Tires
Not familiar with diesels, but I see it has mucho power and torque. Any ideas on what could be expected of performance if stock tires (31" dia. I think) on a 2006 4x4 QC, cummins, 6-sp manual, 3.73 rear diff are swapped for 33"? Will the massive engine torque and low 1st gear compensate for the larger tire and high rear diff??

I did this swap... mileage dropped about 2~3 mpg IIRC, (have the data at work). with the 6 sp you should be fine. have a look at my gallery if you want to see what 33's look like on the ram...

M14,
I'm right there with Steve0
With the auto I'm sure one would notice a little drop in getting the truck out of the whole with the larger tires but prob. not a great deal. When I swapped em out I really didnt notice but then again I was already running with a programmer.
Good luck!

Yep,
The low end did suffer when I threw that 5" exhaust at it but I deleted the cat and did the intake at the same time. There was absolutely no back pressure and the turbo spooled so quick that there wasn’t much there.
Took the intake off and put the stock box back on and replaced the cat and all was well. Still is some noticeable loss on the low end but the BDTD and the QZilla econo chip help allot.
Of course now that I've driven it I've become accustomed top it but at the same time I have "tested it" out of the whole and have beat my share of others.
For everyone out there lookin to spend the money on an aftermarket exhaust (4", 5" whatever) I would definitely not recommend the 5". At the same time though I wouldn’t recommend the 4" either.
Save your money!
If I had it to do again I would just leave the stock 4" on and replace the factory muff with the Aero!
Looking forward I may do the same (swap the 5" out and go back to the 4") but right now I've got bigger fish to fry.
ATS intake, Valve Body and Torque Converter.
This combined with the other goodies already on the truck and I'll solve many issues.
Increase MPG, little / no tranny slip, quicker out of the whole, faster stronger setup! [sm=badbadbad.gif]

RE: Bigger Tires
what you could try is adding the aero inline with the 5" setup. when I did my cat delete + mag setup I also lost all low end torque. and just like you my turbo spooled real quick. Since adding the aero in-line with what I had (basiclly where the cat was) a good amount of low end torque came back. If my bank account supported it, i'd give the 5" aero a try instead of the 4"... the thinking is that it would still flow like w/o the reduction the 4" aero has. right now, however i'd recommend my setup to anyone doing an exhaust change.
