98 gt exhaust
I have made my wife believe that a set of flowmaster mufflers will help gas mileage. We just bought this car this weekend and I love the sound that flowmasters make. Will 2 chambers be too loud? what series do you recommend? do I have to purchase an entire cat back system or will i get just as much improvement by changing only the mufflers? Please help asap. thanks
