Finally got warm enough to install the exhaust, video and pics.
I have to do it manually, I have a STX. Believe me, I know it's impossible, but it's happening, I just topped off about an hour ago and 156miles on 9.121 gallons for 17.1 mpg average, I used to barely hit 75 miles on a quarter tank. I'm wondering if the muffler fell apart internally and was blocking the exhaust flow, it's such a difference, I could not believe it myself. I am not complaining though.
You may be right, I bought the truck in September but was hauling with it constantly at first then by October the winter gas comes out.
