I have an obx header but it from didn't have the 2nd downpipe piece that had the O2 sensor flange on it

if you have the 2nd piece let me know, doesn't matter if it's used doesn't have to be brand new just trying to get my car running so i can make it to work again, lmk

you could easy get one fabbed up at a muffler shop.

think so? i wasn't sure if they could make flanges for the O2 sensor or not that was my main concern if so i'll go check !

All they have to is weld on a bung. The stock oxygen sensor unscrews from the 2 bolt flange.

I 2nd what both McK and Corey said.

Any muffler shop worth its "metal" (I know, bad pun. Here's the correct word for you if you prefer: mettle) should be able to fab one up for ya easy enough.

yea deffinately get one made from a muff shop lol. but i would use bigger pipe. the obx collector is 2.5 i believe but the down pipe is 2". i would suggest making your new one 2.25 or 2.5 depending on the size of exhaust you plan on using. i would also buy some exhaust flanges and take them with you. in my experience muffler shops dont usually stock that sort of stuff.

just got back from the muffler shop they did a pretty good job, welded a new bung for the 02 sensor, showed him exactly how i wanted it to go and it came out good! now i can take the exhaust off whenever i need without hassle
