Sitting at 1/3 tank which means it's time to fill it in the morning.
And about the exhaust making your mileage go up. The engine doesn't have to work as hard to make the same power so unless you floor it that sounds about right. I was getting 35+ mpg in my 95 Celica with full exhaust, intake, and iridium plugs. The Supra's only averaging ~22 right now (according to the super monitor, so it's really ~21 from what I've seen in the past).
