Honestly, embarassing as it is, an AEM wire cover and thats it. I bought my motor off someone who was swaping an H22 in her teg. She put that wire cover on. I'm not the type to put stickers and stuff on my car (not trying to show what I got) but I'm not trippen whats showing under the hood. Anyway, my motor is bone stock with an open Blitz filter and catback exhaust. The sound isn't that bad, I was just wondering if any of you fellas have the same symptom. It sound like it might just be classic integra tb noise.

 

My ls with an injen cai used to do it very loud. The classic whistle. Now that I have a b18c swap, same car, with the same modified ls intake, it does not whistle. it's all in the motor, not the intake.

 

yeam it is pretty common, and it can get very annoying, so your not the only one.
