can some1 shine some light on this for me i must have a brain frezze b/c i do not remember teh difference between a CA spec y pipe from a FED spec y pipe whats teh difference? help plz....

 

the fed has 3 o2 sensors and the ca has 4 o2 sensors, or was it vice versa?? i'm 95% sure that i got it right. you can use the Ca on the fed by pluggin one of the holes and you can use the fed by making another hole in the y-pipe

 

you have a fed spec. no need to worry.
