Question Gears & Muffler Decision Help Needed

I recently got my 1st jeep, and need some advice. It's a 2008 JK 4 Dr, and so far it's got a 4" Teraflex Lift, 35" BFGs, Airaid CAI, and in the next few days a throttle body spacer from Air Aid. I know there's mixed feelings on those, but hey, it was a free offer. So, now my next move. I really want more power, so it's either upgrading the muffler, or regearing. Now, in time I'll do both, but what would you guys recommend 1st? If I go with the gears, should I go 4.88 or 5.13? Anyone know the advantages on either or with the 35" tires? And the muffler, any reccomendations? I like the way the Gibsion split looks, but haven't heard much about the performance. I'm leaning towards magnoflow, but not sure...your thoughts? Oh-also, auto trans, currently 3.73 gears.

I would go ahead with the 5.13 gears, especially with the auto.

Those of you that think you know everything really annoy those of us that do!

I'm leaning that way...by the way, checked out the pic of your jeep for sale-that is a thing of beauty...if only I had a spare 40k lying around here somewhere...

I went with the Cool tech system I like it a lot plus I feel the power better since I put it on! It has a magnoflow muffler too. And it is much better than the stock one for water crossings!
