who has installed a cat? (fc)

ok pretty much i have installed a new bonez hi flow cat. only thing is im not quite sure what to do with the part from the air pump into the cat. it was connected to the original cat so i cut it off. i was thinking take it somewhere to get welded back (thats how it looked to be done the first time)

so basically anyone, how did YOU do it? ive been searching i cant find a write up or anything. ive had this car almost a freakin year and i need to finally pass emissions and im almost there.

by the way i have A LOT more noticable power and response. old cats were shot to shit. also have rb header now installed.

Pull 02, run air pump to the 02 bung and them go toemissions. Then remove when done.

I run a electric air pump when i go to air care my car. I nabed it off of a mercedes ML500. Works great.

i havnt heard this from anyone else...what do you use to run it...and where from? im not quite sure...then again i havnt looked but it would be nice to do it right.

and how sure is this to work? i mean i have no cloggy shitty cats now, i still have very new spark plugs, wires, and i am going to run alchohol again.
