Well, I got an answer to all you 2.2L guys looking to get a little more HP and Throttle response out of you 2.2L's that won't cost you a penny. Basically I removed the factory silencer out of the front of the air box which i didnt think was so big until I pulled it out of there. Looks stock, But It made a huge difference in throttle response, no more sluggish delayed response when you hit the gas, and it sounds better with a nice deep tone when you get on it. hope you all enjoy it, next will be a cheap custom pipe from the other side of the box to the throttle body.

1. remove headlight and headlight bracket:


2. remove the entire silencer assembly from the car, which you then have a huge open space.


3. This is the air silencer. Very restrictive...


4. This is the stock base of the factory airbox.



5. This is the whole on which the factory silencer tube was running though. Now it is just in the open space which if you have factory fog lights the grates will allow cold air to rush in there. If not there is plenty of cold are coming in from the side of the radiator and the body.


finally re-install the headlight bracket and the factory airbox and it looks perfectly stock it will not void any warranties that I know of.



Hope this help everyone, like I said the sound and the throttle response alone is pretty amazing. As far as mileage not sure yet, but I will comment on that as soon as I see what it does.

DarkCobalt13

Moza13-

about to do this to my car tonight.

g5mike

nice easy mod,let us know how it feels afterwords

Moza13-

will do. actually im in the mood, ill go do it to my car right now

edit: Im working on it right now, and the opening seems too small to get this peice of **** out of there. the place where it connects to the intake is like stick in that little hole since it doesnt want to go down any further

I got this far the other night and then the sun went down so I couldn't finish. Let me know how you manage to get it out.

HatedCobalt

isnt there a bolt in the fender well under the inner fender that hold that piece in. actully i know these is.....maybe im wrong....

gtxsport11

will this mod do any good for the GMPP Intake?

Belto

it can help too... check it out,, if you dont like it you can always put it back on

gtxsport11

what about now that i have the fog lights will that allow more cold air to pass through than before with the ls bumper

Belto

hummm? IDK,, with the ss/sc bumper, you can do a custom ram, in that part by using the passenger side fog light hole, but, with the fog in,, I think is the same flow of air, maybe a lil more, maybe

gtxsport11

thanks bro i am hopefully goin to go pick up the balt 2 morrow it will have a new SS/SC Bumper and the GM Lip kit on it along with what needed to be replaced

Belto

Ill be waiting for the pics

gtxsport11

I want to do this to my car, but I was wondering...are there any risks involved in this mod?

DarkCobalt13

none, unless you like driving through puddles up to your bumper. Otherwise its 100% worth taking off!

th0ughtless

Also, would it suck in hot air?

xCobalt05x

I removed that plastic thing down below when i had to pull off the front bumper to put on the bodykit front bumper, was really easy to take off when my bumper was removed.

th0ughtless

I just took mine off. Gives it a better throttle response and sounds neat...lol

Gotenks

This mod was way harder then it looks.. I ended up having to cut out the silencer, as I would have had to take off the bumper to get it unbolted and then out of the engine compartment. This silencer is huge too btw

kingmike06

Omg, I just finished removing mine. It was really hard. for starters its a screw thats under the silencer and and bolt that has to be pull out thats behind the silencer and below the intake filter. It was a pain tring to remove the screws and then tring to remove the silencer without out removing the bumper is hard. You have to take the top part off and then twist and bend the wheel base and bumper.

blktrax

Yes you can get the resonator out without taking the bumper off.

Its MUCH easier to do with a set of wheel ramps and getting the front end up.

Remove the splashguard inside the wheel well and the headlight and headlight bracket, then its very simple.


Be sure to put the splash guard Back on.
