so as of about 500 kms or so ago my car developed a rattling(my car has 6000kms on it)...it only happens at idle after the car has been sitting for a while and you can only hear it if you are outside the car or have your window open...when you are outside the car it sounds like it is coming from the engine bay so i took it to mitsubishi to get them to look at it and they told me nothing was wrong and that it was just normal operation of the vehicle...they told me it was coming from the muffler becuase of there new mesh design vibrates a bit when cold and some ppl can hear and some cant...has anyone else heard this?? i am still skeptical of wether or not its comin from there it sure as hell doesnt sound like it...so i am getting the rrm exhaust and see what happens..should be here in the next 2 weeks along with springs intake and crank pulley
