catalytic converter is my best guess. that whistle noise happens when it gets clogged. my guess is somewhere down the road you'll get an CEL. does this happen like as soon as you hit the throttle and go into high RPMS, and just AT high rpms?

lol. The whistle sound from the intake is normal on our cars. But what i was joking about is that the turbo spool is so loud i cant hear the whistle anymore. Thanks for the input tho

I had a whistle sound i thought it was the brakes at first but after really listning it was air on the door mirrors. Theres a gap in them and when its windy and i get going a certain speed it makes a whistl noise. dont know if this is what you hear though.lol

I didnt have a muffler on and it still did it. I had an CAI which also increased the sound. I had even raced my buddy before i was turbo'ed and he said from outside it sounded almost like a turbo it was so loud. I think its just a sweet noise our engines make N/A while under acceleration.

Whistling....
Mine whistles too, I modified the stock airbox, put on a 60 degree joint and then put on my spectre down in the wheel well, whistles too, sounds more like a ricer now though, miss my short-ram sound but I still get to wave at all the people I dust

yes, it is because the 2.2 is DOHC and is considered an interference motor, and DOHC's make that "whistle" sound...just like the v-tec
