Narrative:

Tower requested a report 2 mi out on left base for 27L, this was complied with. After turning final, the pilot flying suddenly pointed to an small aircraft Y on a converging flight path coming from our right. The small aircraft was in a right turn approximately 1/2 mi away and closing fast. As the pilot was pointing out the traffic to me, he initiated a hard right turn to pass behind that aircraft. We missed by 1/8-1/4 mi with maybe 100' of altitude separation. Our passenger (4) were very quiet. The tower claims to have advised us of traffic using the parallel runway (27R). We do not recall this nor did we acknowledge this.
