i know for sure its not the heat shield. i thought it was at first so i removed the heatshield and checked for any loose-ness. nothing. so i put it back, all bolts on tight and secure.

 

taking in my car next week for the same thing... ill let you know how it turns out

 

paperboy, can u here it when listenin under the hood, or only on sides of the front tires?

 

did you try TSB 10-035?

 

okay guys so i did another test and finally confirmed it. i had my car up on jack stands and started the car for the first time of the day. the noise happened, i immediately got under the car, and found out the problem. its the stock j-pipe! its rattling inside the flex pipe. i could hold the jpipe firmly and the noise would stop. i dont see any tears on the flex section so im not sure whats inside.
im going to remove the j-pipe and maybe see what is rattling inside.

 

makes sense cause i cant hear it under the hood, only on sides, but i have yet to go under the vehicle. if u can hear your pulleys and know its comin from the pulley then tenion pulley TSB B08-049 should fix that.

 

I loosened somr of the jpipe bolts d hit the rattling flex pipe a few time. Tightened everything baxk up and right now i dont have the rattle anymorr

 

Sorry for the spelling errors it hard to type on itouch

 

just wanted to confirm that the noise is gone now has not come back my engine sounds good again
