I just wanted to know if the JIC downpipe replaces the stock o2 housing like the vishnu downpipe? And will it cause CEL? Does anyone that has it know if it is 3 inches or not? Does it also replace the catalytic converter?

I believe the JIC is a 2.4" DP. The US spec one should not cause CEL as it doesn't replace the cat. The JDM one probably replaces the cat, but don't take my word for it. It probably also doesn't replace the o2 housing.

 

zstryder your totally wrong it is 3 inch it does replace the stock cat and it looks like it also replaces the 02 housing.

 

can you post a picture? If you have seen such a DP then I am not understanding why you're questioning what it replaces; its usually self explanatory

 

On the JIc website it specifically states that the downpipe replaces the stock catalytic converter also. I talked to a dealer and he also confirmed this. If you look at the picture you will see the exra bend and it V's out which looks like it will bolt straight to the turbo. Downpipes that dont replace the o2 housing just go straight up and dont have the extra bend and they have a flange.

 

thats a WRX downpipe ^

 

took the words right out of my mouth
