air intake and exhaust input

Looking at replacing the air intake and also putting on dual exhaust. Just looking for reviews on what your running? What you like about it/don't like? What you would change?

Are you running a programmer as well? Those two items don't really benefit unless you tie them in with a programmer.
If yes, a friend of mine really loves the Banks Stinger system. He drove by me in the parking lot before I knew he installed the system and it sounded like his stock exhaust. I asked about drone and he said it didn't do it.
I've yet to do either, except the programmer. One day I'll probably do the exhaust, but I believe the factory intake is as good as it's gonna get, while providing the best filtration.

Save your money, and keep your current air cleaner system. It is the best one for your wrangler!

Exhaust system is a different animal. By reducing back pressure, you will gain a minimal amount of performance, and a slight improvement in MPG. Another advantage is, because of reduced back pressure, your engine will run somewhat cooler.

All the aftermarket intake systems seem to be similar to the stock airbox with a cone filter. You can go with a K&N filter to get a little more flow if you want.

Spend your money on the exhaust. I have done this to a couple cars...What dogger said it correct. I personally will go with the Magnaflow. It is not too loud and I like the looks.

I have a K&N CAI and Gibson exhaust. It's not truly a dual exhaust, but has two exhaust pipes from one muffler. Anyway, I put the exhaust on first and ran around with it for a few weeks. I noticed a very very small increase in MPG. Not sure if its from the exhaust or not. Could be just driving habits changed once the newness wore off. I then installed the CAI, and nothing happened.

To me, it's worth the couple of hundred dollars I spent. My Jeep is louder and gets a lot of attention from other drivers on the road. Not very many people cut me off because if they don't see me, at least they can hear me. I also like loud engines. With that said, your 3.6 or 3.8 liter engine will never sound like a V8 no matter what you put on it, but it's loud enough to be cool. If I were to do it all over again, I'd skip the air intake. I get plenty of noise from the exhaust system and whatever other benefits come with it.

Airflow in this engine does not seem to be limited by the factory intake. Unless the engine is able to pull more air, and willing to do so which is determined by the computer, you won't get ANY additional airflow. And the computer will not let the engine pull more air without a tuner, even if you could create more demand.

Are the Jeeps computers set up that if you reset them (unhook the battery) with an CAI, they will adjust to the new airflow? If not, what kind of tuners would you recommend?

I read that when installing a new exhaust on a JK, unhook the battery so the computer resets itself for the new free air flow.

Thanks in advance!

I think it is slightly more involved than just disconnecting the battery, I think you have to discharge the system. I can't remember exactly what I read but there were more to the instructions. Then it takes something like 50 cold start run cycles to learn driving style. All that said I have no idea if this does what you are looking to do, but would really like to know if it works.

The CAI debate for JK's has been going on for a few years. If you really want to be confused check this thread. After all of this info. and debate you should be able to make your own decision as to what's best for you to do. pentastar aftermarket intake reviews

A CAI doesn't work for me but I do like my cat back dual outlet exhaust. No power or performance but for me it sounds and looks better than the stock set up.
