I just bought my 05 SRT a couple of weeks ago from a Dodge dealer in TX. Under 3,000 miles. I have absolutely zero heat in the cabin coming from the side pipes, and I live in Phoenix. Even the sills aren't super hot. I figure the owner which happens to be the owner of the dealership, must have wrapped or changed the exhaust system. Maybe Mopar? I can't get my salesman to call me back on this, and I stressed that this is a positive thing. Anyone own an 05 with no heat problem, and with no modification to the exhaust system?
