I think there were some changes to the pipes in 09 a redesign to the pipes that go from the cats to the muffler. I think 2010 pipe changes due to flex fuel or some combination of the two changes. Bottom line is I don't think it will fit the 2010
park your truck next to an older model and crawl under there. To me they're exactly the same except that the newer truck has larger diameter tubing. Corsa just knows they changed, they haven't confirmed what changes, that's why they don't list it as fitting yet. I've crawled under both trucks, heck I've worked on both trucks. They both route the same way. I say look for yourself in case I'm wrong,.
