As far as I know it would be. I think the only difference between the two is the cylinder skirts on the 2010 are thicker, so I would assume that the top end and bottom end are not interchangeable between 08-09 and 2010's (I may be wrong in that assumption) but that doesn't apply to what your doing. I also know that for some reason unknown to me some manufactures of exhaust cans like slp have a different part number for 2010's then 08-09. Why I don't know. And of course you'll want to make sure u match the right color injectors to the right color ecu.
Curious to see if anyone else chimes in with more info
