i have a 99 ls i/h/piping.....if i just bolt and weld on high flow cat (carsound) will it throw a code for sure? will my car run worse? do i have to have a o2 simulator on a 99 ls??

 

if the cat has an o2 bung wouldn't it be fine?

 

do the carsound cats have a o2 sensor bung? i just dont want the o2 sensor to pick up too much pressure and throw a code???

chances are they will carry the universal version, so yea you would need flanges and an o2 bung welded on

 

but if i get one with the bung already on it...it shouldnt trip a code with obd2?
