I knew there was a certain year that had a larger outlet. Any idea what the casting numbers are?

Not off hand, sorry. If I can track it down ill let you know. 1 thing for sure there are none being produced. You could step up fairly easily from 2 to 2.25 then step up again under the car. Do atleast 18 inches of the 2.25 for velocities sake
