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?

Re: exhaust leak?

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.

Re: exhaust leak?

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