Well, I feel like it will accelerate faster regardless, no? Haha!
no. a stock motor is tuned to have a cat and exhaust. going straight pipe will reduce back pressure too much and slow it down. the fact that he had to let the car sit for a while before it corrected itself would imply that too much pressure is being built up on the exhaust side of the motor. Cats are the most common cause of that
