no the straight edge of the end of the pipe will actually make less power than the same intake with a filter.Originally Posted by BIG WORM
the velocity stack is designed with a radius curve in place to smooth the transition of the airflow into the pipe while improving velocity in most cases

... so I bought just an ebay intake and put a velocity stack on it and made a filter of sorts with screen door material ( that you cant see ) in btw. the velocity stack itself and the piping.... I noticed a small increase in throttle response.... maybe 1-3 hp?.... it also did sound slightly better in vtec crossover!!!
