New exhaust, should I keep it before rear tires?

[sbc10guy]

I just did a big block swap on my 69 shortbox this winter and am now ready to take it in for exhaust. The truck has had the exhaust exiting before the rear tires since i have bought it and i have liked it. I just ordered new flowmaster super 44s and have hooker long tube chevelle headers on it. Im running 3 inch on it this time around and am wondering will the exhaust be too short if i route it the same or will it sound better out the back? I kind of like the clean look of no big tailpipes out the back. Also should i have an H pipe put in or isnt it really worth it? Any input is appreciated, its going in next week sometime hopefully.
