Got me a shiny new exhaust.
I don't know why either, mine have 3 per bank as well but was excited to see it. I plan to run a wide band o2
I believe those are CAT's or Resonators. The Y looks like a mandrel bent 2.5 ID. I would run it the way it is. Mike might have to do something with the tune tho, not sure.
I bet your tune is ok then. Can't be that far off if it is at all. I recall Mike posting once that you don't need to do hardly anything with the tune when adding LT's. That's what I'm going by anyway.
