OBX headers any good?

i'm looking for some new headers, but i'm not sure which brand to get. i want 4-2-1 SS. i know DC and GReddy are good, but how about OBX? i can get OBX headers and an OBX high flow cat for less than the price of GReddy or DC headers.

how good is OBX? and do you know if their headers and cats are 50 state legal? (cuz i live in Cali)

obx is shit, greddy and dc are ok. if you dont shit money, the best choice wold be a dc w/ 2.5" collector (jdm).
notice: you will need a modified converter.

I've heard a lot about modified cat converters. I'm waiting on a JDM Type R engine to replace my f'd up GSR engine. Well anyways I'm going to need a cat converter that can connect up to the 2.5in collector. I've seen flanges and other parts at stores like InlineFour. Does anyone make a high flow cat that will work with a 2.5in header?
