yes it's auto, i thought it was easy to spin the tires on these cars grrr lol but atleast i'm getting better traction. Well its seoerated enough where the muffler is no longer being used. I was also thinking that might throw off the mpg electronic gauge but i'm not sure
. I'm sure i'm losing low wend torgue but if the gas mileage is true i'll take that trade off! Plus the exhaust tone is sweet:)
