What are some way to get more performance (whether it's more horsepower or otherwise) ouf of the 2.4L? I have a 2009 2LT so I'm wanting to get maybe another exhaust, filters, etc but does it help?

Thanks

A tune will give you the most for the money but I'd wait to do it until to get the other stuff done. Then your tune can account for them.

switching to synthetic oil can't hurt either...
