I find my self down shifting up to stops quite often now that I have a real exhaust haha.I got almost 38mpg on the roadtrip to and from FocusFest this year, and I'm absolutely sure that's about 10mpg better than I get around town, and most of the roads around where I live are 60-65mph with a light roughly every mile or two. I sometimes downshift under bridges just to hear My exhaust spit and pop, lol.
x2!!there isn't a day that goes by that i don't get on it. At least once per trip, and yes i downshift to hear my exhaust, to help slow down, and to make sure that i'm in a gear in case i need the power, cause you know how those lights can change before you get to them lol.
