i got the competition shorties....arent they supposed to come with a Y pipe? mine sure as hell didnt....will the stock one work till i get a new one? also the place that the o2 sensor screws in is solid? i have to drip threw iron??

 

Which ones did you get? the 2055s come with a Y pipe and o2 sensor bung. If your headers have 3" collectors then no they don't come with a Y pipe/

 

it has the 3'' collector and didnt come with a y pipe...has the o2 bung screw in but its solid...i guess i have to drill into it so the end of the sensor will go inside it...has anyone drilled threw? how hard was it and will the stock y pipe work for now?

 

Only the hooker super comp headers come with a y-pipe.You have to have one made becouse the stock one wont line up and hooker doesnt make one.Later.
