I have a question for those of you with the Stillen intake. Does anyone hear a slight whistling noise when accelerating? It only seems to happen from 2k RPM to 3.5K RPM and then I do not hear it after that. I know there are issues with vibrations but it does not sound like anything is vibrating plus I made sure to put rubber around the pipe where they would potentially vibrate.

 

I have no vibration issues or any whistling noise.. Check all your connctions sounds like something is loose.

 

Its weird that it is only noticeable in the low end RPM range....and it's a faint noise but I hear it.

 

Yes and yes.

 

yes and yes what? LOL

 

Yes whistling and yes vibration lol. I put felt pad from home depot on and it works

 

What did you do about the whistling? I check the fitments and it seems tight to me...

 

Did you check the the filter clamps also..

 

I thought it was just the nature of it. It's more of a sucking/ baby turbo sound. I can only hear it in parking garages. Or it could be my test pipes. Haha.

 

the intake doesn't whistle. something is loose, probably your filters or a connection.

 

no whistling on mine

 

It's not that Loud. I can only hear it really faintly in a parking garage if I punch it :/

 

I checked everything again and the only thing I can think of is that the filters were really dirty (I bought it used) and the debris stuck in the lining of the filters could possibly make a slight noise. I guess I'll buy sb exhaust and not worry about anything since I probably won't hear anything but exhaust...

 

Anyone think it could be due to the debris and dirt stuck in the filters I tried cleaning them but no luck

 

If you cleaned them properly then there shouldn't be any more dirt and debris in the filter so that's a mute point
