Thanks man. I honestly don't know I took it to a muffler shop and just told them I want dual and they did the work so I'm thinking it's a y pipe and it's a auto.
Problem with the y pipe is that there is a still a significant restriction in the exhaust. While this backpressure is beneficial on a nearly stock motor, its extremely parasitic to well modified motor that is breathing heavily. (hci, poweradder..etc)
