i'm thinking about upgrading the exhaust in my 2.4l, my first stupid question is: will an exhaust increase my mpg and engine life?
probably another stupid question..but do the exhausts for the 2008 2.4L g6s work for the 2009s?

Dual outlet exhaust won't harm your performance at all.

is there a direct fit, or easy to fit muffler only sold that would work on the 2.4L?
would that make any difference in performance and mpg?
