open exhaust vs. gas mileage...
hey ya'll,
got a question...i've got full 3 in open exhaust on my 98 stx and i get about 14 mi/gal goin downhill with the wind behind me. what should the normal gas mileage be for a stock 98 stx? if it makes a big difference, i'm thinkin about putting a flowmaster 40 series muffler on it. any advice would be great
