Sorry to post this here but I reallly need an obdII 17.5" stock catylitic converter with secondary o2 bung asap, I'm going in to have my jdm itr motor smogged by the <U>state ref</U> and don't have this cat. and I need it to pass the emissions test. Please sell me or let me borrow your stock cat. if you are running an upgraded cat. I'm located in the bay area of california. Thank you.

 

Just a thought here, and I may be incorrect...

But won't you need a USDM ITR header as well? Due to length difference?

 

Yup I still have my stock header. right now I'm running a carsound cat. with dc jdm 4-1 header. But will swap in stock unit once I get a hold of a stock cat.
