as far as gas miliage the best thing for the best price would be a diy intake and a 3"DP cat cut cut out and replaced with a straight pipe same with the muffler. all that would run you about 300$ tops..
for about 400 you can get a 4" system turbo back would be less worklouder and lower egt's
a chip will help with about 1-2mpg alone but they are 400-500
depnending on your tire size/if you pull a trailer a higher gear ratio could be your best bet but thats a big chunk of money.
as for wrapping up the DP the way i have learned it keeps the bay cooler and your pipe hotter. with the increase in airflow i would not worry about it heating up as much as your factory dp.
