ORY shouldn't have any bungs for 02 sensors. After removing the cats, you only have the front 02 sensors left, and they plug into the long tubes.

YUP, LT headers carry the bungs for the 02 sensors, not the ORY pipe.

i didnt get lt yet i got the stock manifolds.

So wait for the LT headers, then install the ORY. It's a waste imho if you don't.

You will free up a little power but nothing worth doing if you don't have LT's. Hooker LT's are going for $2XX on ebay if you look around. Thats what I got and I like them with no issues. I'm not even sure if a ORY will fit on stock manifolds unless you mod

[Darkrider02]

but man the car feels like its running shity like its lost power instead of gain

[blackSS01]

To do exhaust and to do it right, you should really do LT's/ORY/Catback. After that, your car would benefit from a mail order tune. I ran full bolt on setup before my H/C without a tune, but to get the most of it (IE MPG/HP) you want a tune. Probably good for 5-8 hp and 1 to 3 mpg after full exhaust. Thats very rough estimates

well i gotta do mods piece by piece... i have a o2 sensor just left hanging, the 1 on the driver side after where the cats should be can that make the car run like this?

You should have the rear 02's deleted with a tune and the 02 bung on the y pipe is so you can install a wideband 02 for tuning and keeping track of the a/f ratio

[Darkrider02]

if i dont have that o2 plugged in then it would run bad? so should i just put the stock 1 back on?

[blackSS01]

Kinda confused If you have rear O2's hanging, just unplug them and you will get a engine light code for your cats which won't hurt performance. If you have a front O2 hanging, thats bad and will cause your car to run like shit

You should plug that hole otherwise it's kinda lik an exhause leak and it'll start to smell in your car at red lights.
