2011 Jeep unlimited 70th anniversay

Hello, Jeep owners need some help. I have 2011 Jeep Unlimited 70th anniversary edition and I'm looking to do some performance stuff. I want to put Magnaflow exhaust and and AFE cold air intake system. Do these modifications do anything or am wasting my money.

I just installed a cat back system on my 2011 2 door sport. While I enjoy the sound the only gain was seat of my pants and higher clearance with the washtub muffler out back gone. I have come to agree with many on here that performance gains for our jeeps will not be through engine mods, suspension and gearing is were it's at.

In short you are wasting your money if you are looking for performance increases with that. You won't notice anything most likely. The money spent on those 2 items and you are half way to a new set of gears installed. That is the first mod I would make if you want an increase in drive-ability.
