So I've already searched throughout the forum and tried suggestions made by other users, but it's still to no avail.

Vehicle:

2017 Subaru BRZ 6M

Prior to Current Situation:

1000km on bone stock (no mods), and no CEL
500km with Perrin CAI installed, and no CEL

Current Situation:

Getting P219A and P119F after installing Gruppe-S UEL header. I am on a stock map, no tune.

Current Mods:

Perrin CAI 2.75"
Gruppe-S UEL Header

Header Installation:

new gaskets
no exhaust leaks after installation

P219A and P119F were showing up on bone stock before I got mods for the car so I brought it into the dealership to fix it and this is what they have done:

readjusted valve clearance
replaced o2 sensors

The car is free of any CEL on bone stock after the dealership fixed it

I'm pretty confused as to what's causing these specific codes to come up only after installing the headers. If you guys have ran into similar experience or troubles before please share your expertise. I'm stuck.

Any suggestions or ideas you guys have are more than welcomed and appreciated.

Thanks
