i just had an injen cai installed the other day. i noticed that when i'm accelerating i hear a "whoosh" or whistling sound around 2-3 rpms. is this because i haven't changed from the stock exhaust setup yet? thanks guys.

 

no its just the air going threw the intake...happens to most people with aftermarket intakes....I've had a stillen high flow to a frankencar with k&n and frankencar with apexi now all three whistled..at the same rpms

That whistle turns heads, feather the gas just right and it sounds like an SC

 

haha yeah it really does it njmax, I have a stillen intake and it sounds like a turbo when you nail it, sounds like its spooling up, and if you release the gas at the right time it does a pretty loud PSSSHHT, it does turn heads, its pretty funny

 

when i do upgrade the exhaust (thinking of the obx cat) what will happen in terms of noise?

thanks again everyone!

 

I don't think it has anything to do with the exhaust

 

I was dropping off my buddy to get his car worked no and I floored it when we were leaving. When we returned to get his car all the mechanics were standing out front and they proceded to ask me if I had a supercharger. hehehehehehe

 

z, what was your favorite setup of the three you have mentioned?

I had a Frankencar before I switched to the Injen. The FC whistled so loud it annoyed me. The Injen still whistles, but not nearly as loud. The FC sounded more impressive when revving and WOT, and the Injen is more reseverd with a quieter, deeper growl. I prefer the Injen...it looks better, too.

I just had the INjen INtake installed last week. I also get that whistel noise which to me is borderline annoying! My roommates says it sounds like a turbo or super charger but to me it sounds like my brakes are down to the sensor - lol!

It is going to take some getting used ot for me. If I can not take it I am ripping it out! I want the extra boost but I can't take noise! Any other CAI's out there or other alternatives to get some extra horses? I want to add a muffler but I would have to have silencers on it. Any suggestions there also?

I have a 2K1 SE!

thanks ppl : )

@NgRyM@X!

 

that sound of air rushing in is a very nice characteristic of the intake. let the rpm wind down then give it a forceful rev and the whistle can be heard distinctly.

 

wut does WOT mean?

 

wide open throttle

 

I like the apexi...feels stronger and also sounds better.... a lot deeper when above 3000 rev's and light exeleration whistle i like but thats just me

i love the whistling sound of my injen

 

I don't hear the whistling sound unless I go WOT's.
The sound of the Injen intake is very impressive!

 

When I got CAI Injen, I like the sound but when I replaced with APEXI Fliter, it sound much better. I love the whistling sound.

 

I have a brand new OBX catback F/S. Check your PM.

 

I couldn't stand whistling noise and I went back to stock. Basically, at around 2 to 3k rpm with part throttle the noise was constant and very very annoying.... Right at city cruising speed, with constant whistle.... Annoying...

 

Maybe it's one of those electronic devices that make it sound like u have a BOV
