I have that weird itch to modify my work VAN. We all know that if you setup a vehicle to breathe easier it'll be more efficient, thus get better gas mileage. Off a 22 gallon tank, I run between 250-300 miles weekly, which at 2.58/gal, costs the company 50-60 a week in gas. I've been contemplating a short ram, headers, (yes with an s) and a full 2.25-2.5" exhaust. Not to mention getting some better rims/all season tires since it rides on 15" steelies with hubcaps now. I'd see no monetary gain other than using less gas, even though I don't personally pay for it. Am I crazy to think about modifying it?
