I dont mean to come off like a fanboy because i sold my 370z for a 335, but the power in the 335 comes on way faster than the power in the 370z. The fact that it is a turbo car is irrelevant. The turbos are very small in the car (like the size of a donut) and they have instant boost. In fact in the n54 motor, they had to take special care in tuning the car to keep the wastegates shut for slightly longer, since the turbos are so small they would actually just be in full boost all the time.
the muffler adds 0hp/tq on the 335. Sounds about right that you'd pull on him 40-80 stock, but i doubt it if he had a tune. Keep in mind, there are other factors besides hp/tq. there is also weight of cars, gearing etc that will determine which car is faster.
