I've done a lot of searching and I'm finding it challenging to locate info here on C.A.R.B. legal intakes, headers, or exhausts for the 2011 Fit. Ten years ago I would have packed the engine bay with illegal modifications and not cared, but alas...I'm a bit older, and since I'm a Commiefornia resident I want to keep it legal so I don't have problems with the fuzz, or smogging.

Does anyone have info (links, part numbers) for C.A.R.B. legal power mods specifically for the 2011?

 

Maybe just go nuts, keep your old parts and deal with it in 6years when you actually have to do your first smog.

 

Yep no worries for six years! These "CARB" legal intakes are usually not a problem for visual inspection here in California. As long as all the vacuum lines are all connected and no CEL, you are all good. Only thing I guess where it can go south is with PD, SD, CHP pulling you over and wanting to pop your hood. But again they need a reason to.. Basically street racing or acting like a fool on the road. But for pure aesthetics under the hood and some noise from a modified muffler you will be safe.
