  • Fits Perfect on my 2009 Acadia.
Size: 2009-2017 Traverse
I was a little hesitant about buying it at first. I was skeptical about the reviews and the excellent price, but it's really worked well for me. It's been running for a few months now and still hasn't given me any problems, so I highly recommend it to anyone who needs a catalytic converter replacement at a good price. ... show more
