When i give it good gas from a stop you can hear a quick hiss from under the car when it shifts and you can only hear it on the first 2 shifts. Only really hear it when window is down. Hope it is normal because i like the sound lol

Is it?

 

Normal.

 

It's normal in the 07-09 sedans. I am not too sure about the 10-11. I believe the noise actually comes from the exhaust somewhere, not the engine. I've mentioned it to the dealer when I first started driving the car, but I learned that it happens in all the sedans. Even every loaner car I drove had the same noise under hard acceleration. So I figured, it's normal.

 

Glad to hear it's normal because it gives it that sportier sound


It sounds like it's under the car..is it the exhaust?

 

EVERY problem you with you car have is NORMAL. the dealer will say the same.

 

If you get some BERK hfc's, you can get more of the hissing that you enjoy so much!

 

Normal. The sound goes away after you install the new exhaust.

 

Won't be for a while but i am already looking forward to it

 

its the supercharger u got underneath there..;-P
