I have 2008 Dodge Grand Caravan 4.0L SXT and I have the same problem - irritating pinging noise from the exhaust when cooling down and even when driving. It seems that the noise is coming from exhaust pipes under car. Does anybody think, that exchange of complete exhaust system for some aftermarket or sporty-sound exhaust will fix this problem? My 2001 Dodge Grand Caravan 3.3 never did this noise....
I am really disappointed with 2008.... Please let me know..
