hp and mpg increase by doing dual exhaust?
hey everyone i have the 1990 3.8 liter thunderbird base model and want to take the dual exhaust/exhaust manifold/headers off of a supercharged thunderbird at the junkyard (that has the same engine) would this be worth the hassle? how much torque or horsepower would i have increased along with my gas mileage?
