What have ya'll done for performance on these 200HP monsters?

I've put a K&N on mine, I maybe noticed a small gain in the "seat of my pants Dyno"

I'm running an Amsoil EA drop in filter and modified exhaust. Exhaust was the biggest performance booster.

is it loud? Don't like a loud exhaust unless it has power to back it up, reminds me of those Honda Civics with "coffee can" size exhaust tips

My "system" is just an 18" glasspack ($18) welded online the stock pipie under the driverside floorboards just forward of the evap canister and I yanked off the big ass boat anchor of a muffler from the crappy factory location.

It's loader than stock but not obnoctious. Has a nice grumble and not rivet at all. If you want something a little quiter pick up a24" one instead.

The Superchips programmer does pretty well on the JK. Elimates the slow response time of the gas pedal.

Intakes and exhausts aren't going to do anything. The only real way to get performance is to drop a Hemi in it

Anyone used that new programmer yet for the 2010s? Like? dislike? worth the $300?

The more I drive the wifeys jeep, the more I say it needs some more stuff. Exhaust and programmer is next on list. Just waiting on some opinions. This jeep in a headwind at highway is horrible.

An exhaust is not going to solve your issue of the need for power... a couple of horsepower at best, even with a cold air intake. Unless the programmer and chip manufactures have "certified dyno results" my experience is it's mostly snake oil. I chipped my Crossfire, it's a psychological seat of the pants gain at best. The chip maker promised 15~25 HP gain... no way. Re gearing is the best way to go, I noticed a real difference going from the 3.21 gears to 4.56 gears. LOL... I can now drive over a highway overpass with out loosing it. But, if it's true power you want, a supercharger or a hemi is the only real way to go. Air intakes, exhausts and chips are a cheap ricer boy way to try to get power. You can add the ricer's favorite... nitro for short bursts of speed. Remember. power costs... lots of $$$ = real power.

In my experience, TB spacers are a pile of snake oil as well. They work with some older model throttle body fuel injection systems, but past the Renix era they do just about as much as trying to push the Jeep. Think about it this way: the idea of the spacer is to increase the internal volume of the manifold. Using an XJ as a reference with a 99+ intake, the manifold holds a little over 4 liters of water. A throttle body spacer adds less than a tenth of a liter.

What I've found actually works to improve mid-throttle response but not horsepower or torque is a bored out throttle body.
