So I was reading a post about debaffling today and thought, why not...

It took me all of 15min to de-baffle. Contrary to what I thought, no dremel was needed, just a socket wrench and a flathead screwdriver...

I took some pics and will post for reference...

To be honest, I took my car around the block and didn't notice any difference in sound (I expected a throatier sound). I already had a K&N filter installed before...

EDIT:

Step 1
Undo the clips that are holding the box onto the engine intake...


Step 2
Undo the two bolts facing the fender that hold the box down. (There's some other unit that is held on by the screws so just move it aside and put it back at the end.)


Step 3
Take off the sleeve on the front that actually brings the air into the box


Step 4
On the rear side there is a piece you have to undo with a wrench. It looks to be a sensor of some sort. (I forgot to take a pic of that but you'll know what it is because it's the only thing holding your airbox from coming out)

Step 5
Once you pull your air filter out, you have to remove the baffle. I didn't take a pic with the baffle in, but it's the large piece that's connected to the tube you undid in step 3. See these two pics for the spot where it is clipped in. I used a flathead screwdriver to pop this tab and if fell right out.




Presto, just put it back in using the reverse order of steps!

I have a 1993 325i and I was looking to debaffle it, but when I pull the filter out of the box, there is nothing to remove. Am I doing something wrong or looking in the wrong spot?

Furious,

I'm thinking about buying "openwheel"'s CAI and front strut bar.

You know anything about his stuff? He said the strut bar is eibach and the CAI is some sort of no-name but with a DINAN filter and water protectant sleeve....

How do you upload sound clips? I can try it. But it would probably be better with a car that wasn't a '92.

I thought it was Borla....

I'm not sure how good of an idea it will give people but I'll try. Going out right now.

I'll do a rev in the engine bay so you can hear the PSS noise. Then inside the cabin so you can hear it there too.

Here you are Kevin...

Maybe it's my speakers but I can barely hear the engine in the first clip and not at all in the second...

It is a Borla tough guy. A Borla Stainless Steel (SS) exhaust. It is just quicker to type SS than Borla Stainless Steel. But thanks to you, I had to type it twice-

geoff: Your link didn't work for me, and I was all excited.

It doesn't even play anything on my computer when I use that link. Yeah the quality is a little lacking to say the least.
