Figured that I should post how to remove the silencer on a new thread for everyone. Take a look!
First off, remember that Chrysler's factory system is indeed a cold air induction (CAI) kit. Chrysler's CAI just has a big silencer behind the bumper. Remember, just because the aftermarket sells a CAI kit doesn't mean you don't already have one, or that its significantly better than what you have. If anything the stock air box (without the silencer) gaurantees you will have a high flow CAI setup and also ensures you still get air from behind the bumper and not inside the engine bay.
Well, here we go:
1) Safely raise the front of the car 4" or so. I have a set of $30 heavy duty ramps from WalMart for this task.
2) Open the hood, remove the air filter from the car. You will see the top of the silencer now. Stick your hand in there to see how restrictive it is. You may wish to remove the lower air filter housing, it is held on by a bolt near the headlight (right under your nose) and a rubber knob that presses into the body. I don't believe it is necessary to remove the lower airbox, though.
3)From under the car, remove the two front bolts that hold plastic cover below the engine, or remove entirely if you wish.
4) Remove the bolts that hold the bottom of the bumper cover to the chassis, there are about 10 of them. This releases the black liner that is sandwiched between the bumper and the chassis.
5) From the driver's side wheel well, take a forked tool (used to remove door panels, I have an "OEM" brand tool from Autozone for this: $6) to remove the three push pins that hold the black liner to the bottom of the car. There is one near the painted fender and two more further down the wheel well in the same general vicinity. This will remove the top half of the black liner on the driver's side.
NOTE: The push pins are made of two parts: a pin and a base. Only remove the pin with that forked tool, with the pin removed, the ringed base will then pop out when you pull the black liner out.
6) Pull the black liner out from under the bumper and from under the driver's side wheel well.
7) The silencer is now in plain sight. There are two rubber knobs that press into the body and a hook on the top. Pull firmly and wiggle on the side with the rubber knobs to release.
8) Reach up the body of the silencer and you will feel a bolt at the top. You may not find it, but near that bolt is a hook in the silencer that is released by a quick yank down. Having a second person to push on the silencer from under the hood is a good idea.
9) The silencer will pop off easily, it happened so quick on mine I don't quite remember how it happened! Now reinstall the black liner, pressing it inside the bumper and lined up in the fender with the corresponding holes.
10) Reinstall all bolts on the bumper and the pushpins on the fender. Reattach the two bolts that hold on the lower engine cover.
11) Reinstall the air filter and close the airbox...
That's it, you're done! The difference is mild, but worth every penny, since its essentially free! You can install a K&N filter with this mod and you might net 2-5hp more, or the same increase in power an aftermarket CAI kit would.
