I have a 2009 Pontiac Vibe with the 1.8L that has a cracked exhaust manifold. I see 09 Toyota Matrix 1.8l manifolds online but nothing for the Vibe or a compatibility listing. Are they the same?
However, sometimes I go to car-part.com an online searchable database for junkyard inventories, and they use some interchangeability reference. When I looked up 09 Vibe 1.8L manifolds, it only gave me Vibe ones, when I looked up the same for Matrix it gave me Matrix and Corolla manifolds, but no Vibes. Can't imagine what the difference would be though.
Maybe you could check car-part.com to see if there's a junkyard near you that has a Vibe one
