Yes, a blown y-pipe will cause that. It's a boost leak so you're getting all the fuel into the engine but not all the air.

Check the bellows on the sinister pipes.. if they have exposed braiding internally.. there have been a few failures documented..
lets get your old ones fixed..

are the slip joints leaking? Have you crawled under and checked for soot marks with a light?
