300c air silencer removal instructions (Moved) - Page 2

Here is a before and after picture if you cut the two pieces off of the bottom of the silencer. There are two holes about 2.5" wide after you cut out the bottom. I don't know what to do with the two holes either. I want to use them to get the cold air from the grill inlet once I cut it out more. Any suggestions or ideas.

Here are some pics of mine. Silencer off and the inlet to the airbox as if looking down from the bottom of the air box. Note the angled pop can plug to match the internal plastic flange as to not in any way hinder airflow. I used the thicker aluminum sides for three point fixation and finished off with a layer of silicone.

I also have decided to cut & put part of the silencer back. To cover the two holes I went to Home Depot & in the Plumbing section I bought 3" PlumbQwik Plug,a 2x2 fitting & screw in cap. I then sealed the cap & going to wait to it dries to put it in. I'm going to put in a mesh grilled for better airflow.(Homemade

). Here are some pics.

Guys,

Why are you putting the silencer back in there? Even with the resonators removed (the plumbing caps are very clever, BTW...used those on my Mark VIII) that tube is a restriction.

I have the silencer right next to me, not only does it NOT provide a straight shot to the airbox, it isn't a constant diameter tube! That elbow you see is a restriction!

The airbox sits nice and tight to the body even with the silencer gone. Having the silencer put back in doesn't change anything except that the airbox gets less air! The area (and surface area that can ingest air) of the hole in the body is bigger than the neck in the silencer.

Here the pictures show the steps Pro-5-Oh outlined...

2805 - Remove the air box bolt.

2801 - What it looks like once the air box is removed. I circled the "exhaust port" from the silencer.

2806 - In the wheel-well are the retaining push-pins. I popped my out with a pair of needle nose plyers to grab the pin.

2807 - Removing the bumper screws. I didn't remove all the screws holding up the front part of the under-sheild to the bumper.

2808 - Removing the retaining bolt. Notice the plastic "hump" that helps protect it from scrapes. I only removed the driver side one.

2809 - Pull back (or remove) the under-sheild from the bumper and wheel-well.

2811 - There is a bolt way, way up the side of the silencer. I had to stack a couple extensions on to reach up there to unbolt it.

2812 - Jack up the car. The silencer is bigger than the gap between the bumper and the floor. You'll need an inch or two to get it out. You might want to get the jack out and try it. It's pretty easy once the jack is loosen. (If you're not going on a trip, dump the spare - damn that thing is heavy!!

) There are special places where the jack needs to be positioned. Make sure you put blocks behind the rear wheels to keep the car from moving.

2813 - Just yanked down on the silencer and out it will pop.

2814 - Just a bit of fanagling and it's out.

While you are under there and the under-shield is off, if you want to pop out the driver's side lower grill, here's how...

2817 - Remove the retaing clip. My finger is on it (oh, yeah. Something on the plastic pieces when removing the silencer can scratch the hell out of your hand - were some gloves for protection

).

2818 - Once the clip is remove, pulling bit on the bottom so the bottom clip - which are molded to the bumper - disengage.

2821 - The clip and the plate removed.

Now put everything back in...

2820 - The "space" left after the silencer is gone. I'm not going to cut-up and put the top part of the silencer in there. The guides around the bumper guide cool air cross the radiator. And the fact that I yank the lower grill out will allow more air into the void. Good enough for now.

Later, I'm going to try and manufacture an "air guide" from the lower grille to the openning into the air box. Guess it's time to learn about plastics and possibly fiberglass.

Enjoy!
