04-05 have the stage one fuel injectors but not the pcm.

 

unscrew the sensor from the bung but leave the wires connected to it (Pluged in). You have stage 0 pcm so you will throw a code anyway so that wount be what you want. Mightaswell drill the hole and weld in the bung.

 

I have stage 2 I never got a code the way I did it but I thank like motorboy1 is saying as long as the O2 is still connected you wont throw a code. But the drill and weld will keep the origional O2 out of the way and still in a position where it cant come lose or something like that. Its really a simple mod on the exhaust.

 

well then im basically screwed. i am not going to try to drill into an expensive *** exhaust myself, nor can i weld anyways. so itll just get messed up, and theres not 1 decent shop or tuner garage in my area i think i need to go to a new state

 

get stage 1 2 or 3 and youll be fine. but there goes more $$$$$

 

you dont need a tuner shop you need a good metal shop ormachine shop or motercycle shop for that matter. Its the what you got to pay to play! Yes an expensive *** exhaust but what about when you do a dtec or apexi neo and you need to cut into the wires to the pcm then what. Better to start on a down pipe that can be replaced then something larger. Shoot send it to me at your cost and I will do it free and gaurentee that it will be good to go!!
