    Question concerning air flow on my 2010 Jeep Wrangler engine. What should I do first to increase engine air flow, install a cat back muffler or high flow air system? I would like a little more HP and torque without breaking the bank. I purchased this Jeep with 17K miles on odometer and have no owner's manual to tell me the size of the engine. Is it a 3.8 or 3.6 liter. How can I tell the engine displacement?

    You have the 3.8 as the 3.6 wasn't available before 2012. Headers and exhaust make a better difference than an intake. Depending on what level of modified state your jeep is in, such as tire size and lift, you might want to consider changing the gear ratio.

    Chris is correct that have a 3.8L engine. Doing the just the breather will make a "small" amount more power than doing just the cat-back. (as we are talking about a cat-back system, headers are not an option. However, you will get no real performance differences unless you change both. And then you should reprogram for best results. Save up an extra month and just do both is my advice.

    Personally, I would get a tuner as my first step. It will be required to properly adjust for the other things you mention and has the possibility to make the largest difference in your perceived power, "IF" you have an auto tranny. (some of the tuning changes make a bigger difference with the auto.) I suggest the Superchips tuner. I have had great results with one.

    As for a manual:

    Tell us more about your rig. It might help up offer better advice. (ie. Tire size/gear ratio/auto vs manual tranny?)
