with my QTP closed(3" dp)I get 330 to the wheels, open, 442whp. makes a huge difference. put an extra pipe comming off the valve and weld a piece of metal from the new pipe to the stock exhaust 3/4 way to the rear. this adds support.no more vibration and the exhause dumps towards the back 1/2

These numbers are probabley with the stock exhaust vs open. The horsepower numbers he quoted are a difference open and closed, not the gain over a good high flow TBE.
