I have a 2005 that I bought new to primairly tow my racecar trailer with.So far it is more than I ever expected it to be.I have installed a K-N air filter system that my friends at K-N gave me,and it increased gas mileage by about 1.5 mpg w/o the trailer,and I will tow with it this comming Saturday and see what it gets with the trailer.I have also installed a pyrometer and boost guage and now want to do something to the exhaust.What are my choices and what will each of them do for mileage and power? Thanks in advance for the benefit of your experiences.(PS-I plan on some sort of box after i get some baseline numbers from the new exhaust system)
