i seriously need turbo help

i need to know where i can get an downpipe for a t3 on integra ls with an o2 sensor bung i cant find one anywhere...anybody know where i can get turbo manifold/downpipe combo?...

Why dont you just make your own DP? It would be easier and cheaper than finding one, cause chances are that you wont get it cheap and it will have to be shiped to you.
