auto or 5 speed? either way, if you don't know, you've got stock gearing. i'm assuming automatic with 3.55s if you swapped in a 44. you would benefit a huge amount when wheeling if you got your axles geared....night and day difference. it's expensive, but i believe it's probably the single best mod i've done to my jeep... long arms would also be a nice addition, or at least drop brackets, being that your lift is 6.5". it would help with your flexing an unblievable amount. also, if you want to stay at 33s, you definitely don't need to be that high. and also along the same lines, if you wanted to, you could fit much larger tires with trimming and possibly bumpstopping. for example, on my 6.5" lift i've got 37" creepy crawlers, just trimmed fenders and rear bumpstopping, and no rubbing...
and about the exhaust, if you want to get the flowmaster sound, just use one muffler and sell/give away the second...just swap out the stock muffler essentially.
