I have a Cherry Bomb "Turbo Muffler" on my car ('92 Civic) that I put on last summer, and its really starting to get on my nerves. I was thinking of getting my stock muffler back, but im wondering if my mpg will decrease any. I've been getting about 43 mpg on the highway, which is above the normal 40, so im wondering if the muffler was helping with some of that. Will I have any change in my gas mileage if I go back to my stock muffler?
