well, I got my EST intake installed. Sounds great, not as loud as yours but I love the "blow off" sound it makes when letting off the gas at lower rpms. Car deffinatly seems faster and possibly louder, although I did not rev the engine before I installed the intake so I assume its louder.

 

Thanks guys

 

how much was est air intake?

 

$200 or so
edit: you can also you the coupon code: volvospeed

 

With tax it will run you about $200.

 

hey s70, with the EST intake is that the turbo you hear when you let off the gas? IE, between 2000 - 3000 rpm if I let off the gas I hear a pssssh sound. The only thing changed is the air intake. Any higher than 3k and i can really hear it over the engine. My original thought was that it was just the air intake, but when the car is in nueteral it doesnt make the sound. Does the boost not engage in neuteral? and does it cycle the air back into the air box?

I can get a vid if it would be easier to understand.

 

Air intake and turbo sound yes.
