Exhaust leak

Hi guys, I was wondering if an exhaust leak would cause me to lose gas mileage. I'm only getting about 20 mpg which is way below what it should be
Yes, any leak in the combustion chamber will lead to less than ideal combustion which affects the power output and the economy.
My question is how do you know that there is an exhaust leak....have you run a compression test, or better yet a leakdown test?
