Hi all,

I went to have a look at a near new Chrysler 300 S today at Berwick Chrysler Jeep in Victoria AUS.
I was relay pleased with the ride and comfort but I was a bit disappointed with the response of the 3.6L? Admittedly I haven't driven a car this heavy before but I thought it would pack a bit more of a punch. Is there any relatively simple upgrades available like headers or air filter that will improve this but not affect the warranty?
I will have steer of a few more models before I make my choice but any input would be great
Here's what I'm looking at at the moment
