rear end gears

How much effect would a 3.31 rear end have on my 3.7 manual in terms of performance and mileage

Most 3.7's came with 2.73 gears, so these will definitely wake the car up. I ran 3.73's in my 2011 v6 with the manual transmission, and fuel economy only dropped about 1 mpg. You should not see as big of a drop with the 3.31.
