Funny Exhaust Noise
 
I just purchased a 2012 Jeep Grand Cherokee SRT8. In driving the Jeep it is awesome and is everything I expected. I also own a 2002 Grand Cherokee Laredo. My question is; Upon deceleration of my 2012 I hear this annoying gurgling sound coming from the front passenger side of the car. Upon accelelaration it goes away. I am wondering if there is an exhaust leak somewhere? Also when I am sitting in park and rev the engine I hear a loud snapping noise that happens at the top of the rev. THe gurgling sound did not start until after I reved the engine one day. Please assist me with what it may be

Sounds like the snapping noise is the active exhaust valves closing shut after the rev. The other sound could be the MDS kicking in under light load. The exhaust note changes when the MDS kicks in. The MDS sound quiets with mileage. One way to test the MDS sound is to drive with the paddle
Shifters as it disables the MDS. Recreate your speed and slowing down pattern but while manually shifting. Well, it automatically will downshift while in auto stick.

I now hear the noise coming from the center counsel. When you put your ear to it I Hera the sound. Any advice would be greatly appreciated.

I posted on your other tread ,It's a crack or leak at connection.But I think Mongoose is correct.It's the ECO it drives me crazy,If I have passengers they always ask what is that sound.Man I have tried to bypass that thing it is in the program.Lets hope we can turn it off with a hand held!!!!.I was the first 2012 jeep SRT8 in california I had that car at the dealer 3 or 4 times when I first got it finally they said its the ECO!!
