Which codes commonly pop up after header installs? I have 4:

P0496: System Flow During Non Purge *** Vapor Canister Purge Valve Ill be replacing for like $25

Then:

P0420- Catalyst System Low Efficiency Bank 1 (Passenger side)
P0430- Catalyst System Low Efficiency Bank 2 (Driver Side)
P2099- Post Catalyst Fuel trim System High Limit Bank 2 (Driver Side)

The P0496 is not a code because of the headers correct? While the other 3 are I believe. And Which Codes are eliminated if custom tuned by HP tuners?

Have you checked for leaks? Reading on other forums that helped some but Other says that the p0420 p0430 codes plus the P0299 will need to tuned/turned off.
