went from stock exhaust,header,muffler,piping,resonator
 

I got new ss headers, magnaflow muffler,resonator, and piping increased to 2.5inches, same cat
Tripped many codes
Ho2s heater resitance bank 1 sensor 1
Ho2s circuit insufficient activity sensor 1
02 sensor heater circuit ank 1 sensor 1
Ho2s heater control circuit bank 1 sensor 1

Also the original heat shield was i.creased from just the cat to stretching from the rear sway to right over the resonator.
Lemme know your input,
Should i meed a tune or what. Its all sensor 1
Also
Where is sensor 1 located.

Sensor 1 is your upstream sensor, the one in the header. Did you manage to keep your SAI intact going from the LAP to SS header and downpipe? I was under the impression they weren't interchangeable. The sensor is probably just unplugged.

I will add that the sensor closest to the headers was unplugged. I plugged it in. Reset the battery and the cel stayed off

Well there ya go. That's solved. Congrats on the exhaust change.

Sai? The piping connected to the resonator to the headers is still old i believe.

I thank you on the congrats lol also with the exhaust change should i need a tune or can i wait till i get the turbo and internals installed. Wouldnt believe i need a tune with an exhaust and headers .

2 pics i just took of the headers mounting bracket with downpipe to res. Everything bolted up properly. No problems other than a thrown sensor 1

Header

for the love of God yes, there is only one header.

My bad dude. OBVIOUSLY . Theres only one header.

Well, technically speaking there's 2. But one of them is an intake header. ;)

Alright threads over, any site admin can get rid of this if its not needed lol simple looking around was needed
