Intake silencer delete

I got this from GrimmSpeed on gencoupe.com:
I know a few of your were looking for instructions on how to do this so here it is. The first step i've included(removing ram air) is not needed unless you want to premanently remove the ram air. Removing the ram air will get you even more turbo noise but you will be sucking in warmer engine bay air leading to lower performance. Taking the silencer(s) out will yield a bit more turbo/intake sound.

Tools needed:
Philips Screwdriver
10mm Wrench
Pliers

Remove ram air. As stated, you do not have to do this unless you want to keep it off.




Remove top portion of OEM airbox.




Remove breather lines.



Annoying up-side-down hose clamp. It is easier just to take off the hose clamps on the other end(previous picture) than to try and fuss around with getting the left clamp off. Of course its not to hard to get this off, just annoying so i bypassed it for the directions.



Loosen the 2 hose clamps that attach the 2 piece inlet hose to the intake silencer.



Intake silencer that we are taking out. Take it out.




You will need a 2 3/4" ID pipe that is about 2 1/2" long. Try to get a pipe as close to 3" OD as possible.



Insert new pipe into 2nd piece of turbo inlet hose.



While we are in here, might as well take the 2nd 'mini-silencer' out. It forgot to get a pic of what it looks like after you flip the mini-silencer over and stuff it back in.



I have a vid coming here shortly of the engine rev'ing...you can definitely hear the induction sound more prominently than before. I'm guessing you'll pick up a little power as well since you do not have this smaller ID restrictor pipe messing up with flow.

I hope this helps!

Justin"

I would like to say thanks to Justin (GrimmSpeed) & gencoupe.com

Excellent write up!
I helped a friend do this on his car this weekend... he said it really made it wake up.

When we did this, though, we didn't have to remove the ram clip... we just took off the top of the filter box, removed the vac hoses, and removed the clamps. The top end just came right out, and it was no more than a 5 minute job.

I've done this already as well and it makes a huge difference as far as how the car sounds. Definitely can hear the stock BPV and the turbo is a little bit louder as well. The car feels like it responds better as well as the turbo seeming to spool slightly faster (200rpm sooner). Great cheap mod to smooth out the stock intake track. Thanks to Tufast for transferring it over here from gencoupe!

Are there any negative effects from removing it and not replacing it with a piece of straight pipe?

I'm pretty sure the straight pipe is so you can put the 2 inlet hoses back together.

I see no ill effects from this mod, but then again no real positive effects other than sound.

Yeah I see it now. The clamps for the hose are on opposite sides of the silencer so I would need that pipe to put the intake tube back on.

Go to an automotive store like auto zone and ask for exhaust pipes. They should have an assortment of lengths of pipes and they should all be labeled with the ID size and OD size.

Also, check with your local muffler shops / repair shops, they have scraps laying around that they will give away a lot of the times. If you're really hard pressed to find a piece, I have one from my stock intake someone can have if you pay for shipping.
