haha after my airbox mod it became more noticeable. A guy driving an SRT-4 asked me if it was supercharged....lol

 

Yeah the sound might be the resonator cause I had the sound and after I took my resonator off it went away

 

yeah same here withme when i put striaght pipes on my car cut the resonator off and since then i never heard it again and every now and then it gets a noisy ass whistle at idle but that is the throttle body and i have a quesion for you guys when do you guys usually change out ur sparks? that whistle is a combo of the EGC valve and that resonator pipe haha !

 

I hear that noise as well around 5000+RPM and WOT.

 

watch/listen to my vid, you can clearly hear the noise you all speak of. Its a good noise in my book.....

P.S. This is with just the air box mod and a good filter, and of course magnaflow exhaust.

 

my cavy with a CAI used to do it all the time, i cant count how many times i was asked if i had a turbo, it was that loud.

 

yeah mine doesnt do it any more now all i get is a whining noise but thats just the motors tec kickin in but its got to be the resonator or the EGC valve but i cant figure out why mine doesnt do it anymore im so confused becuase since i modified my exhaust and took out the resonator pipe i never heard that noise again it drives me nuts

 

Uhm... motors tec? I hope your not refering to v-tec like hondas have. Thats Variable Valve Timing or VVT, which the LE5 2.4 engine has. Not the L61.

 

^^^^^^^

 

whatever the hell its caled haha try not to bust my chops so hard next time becuase i worded somethin wrong will ya haha i wouldnt have a clue other than the things i said what that whistle could be

 

Ok my 2.2L does the whistle as well from about 5k up, under mid-hard acceleration.... a little more pronounced with my GMPP CAI. I have lots of friends with 2.2/ 2.4 and 2.0's but I'm the only one making this sound. BTW: mines a 2007.
It hasn't brought me any trouble, but I can't seem to nail down what it is either :S

 

Yep my 2.2L deffinatly makes that noise i love it!

 

I've noticed that my car makes a whistle at partial throttle no matter what rpm or speed I'm at, I only noticed after I cleande my throttle body though. It might have something to do with the fact that I removed all the black gunk around the throtle plate. Maybe thats why it whistles now??

 

that could be very true as redbasebolt put it it could be build up of gunk in the throttle body but as soon as i took my stock muffler and resonator off it went straight away mnostly and then when i topped my car out it stopped completely now all i hear is the motor whining at me when i hit er

 

I wasnt tryin to be mean or smart. was mostly jokin but also tryin to correct you. My comments need to have a perm. goofy face or something cuz im just a goofy person. None of my comments have a ******* intent.

 

have driven 3 2.2s in the past when my 2.0 was in for warranty work lol and they all make the whistling noise...sounded like a tingy metallic sound to me

 

I haven't really noticed any whistling noise with my 2.2.

Mines an 07' LT2 with GMPP Sport exhaust and the 2.2 airbox mod.

 

All i know is that i gets looks weather its good or bad. I like it.

 

wtf? ive owned several dohc motor vehicles. the cobalt is the one and only that made this whistle noise, which i believe is from the intake and the resonator is unable to quiet and thats why people notice the noise more after installing a different intake.

and have you ever driven or been in a honda with vtec? vtec doesnt make a noise, you get a different exhaust tone, and if you have an intake on it, you get a loud pitch from it. ive driven an integra gsr which i helped work on including a vtec controller. ive also been in several civic si, a turbo integra type r, and a civic with a b20 bottom end and b16 head thats n/a

 

ive had the whistle from factory.....the intake made it a little louder but not much....i have no idea what it is but i like it....

 

I cant believe some of you guys dont like the whistle. It sounds sweet. Not ricey at all. Most cars with a CAI will wistle. My buddys 04 F-150 has a sri and it whistles nice and loud.

 

yeah its all good i just took it wrong i just worded that one wrong thats all its all good dude, yeah we all get goofy streakes haha

 

yeah mine whistles too

 

yea...my 2.2 whistles too and i think it is the way the car was designed...i know they didnt say "hey lets make the 2.2's whistle since the supercharged ones whine" but the way it was built and put together is what i mean and mine does it around 3,500 and up

 

yeah wouldnt that be great if they siad that hah wow that be nuts haha but i guess they did but once i put the intake on it screams at me at idle to like 2000 then stops i took off the res and all that jazz haha
