dual exhaus for a 94

well as long as you keep the pipe diameter the same....it'll add more weight and a bit of backpressure cuz you'll have 2 mufflers.
so lets say.......2.25" pipe from the cat to the Y pipe - Y pipe needs to be about 1.25" to each muffler......any bigger and you'll be losing considerable amounts of power.
