exhaust leak?
 
my jeep is making an annoying rattling kind of noise at idle and low rpms. i only notice it when its in the garage or im driving with the windows down. at first i thought it was pinging from using 87 oct so i switched to bp 89 oct and its still there. anyone else have this problem?

Its the Hemi tick. Its the normal operating sound of the MDS. Press the tow haul button to reduce the noise but I must warn you, you will see a reduction anywhere from a half mpg to a full mpg.

does a cai and exhaust drown it out at all?

The exhaust makes it more noticeable. Just hit the tow/haul button. So what, whats one mpg less? :D
