HI....I am new to the forum,but i have a 95 GS auto.I am thinking about ordering the obx headers but are the o2 sensors direct fit?Will i have to do any custom work?

Welcome. You'll need to lengthen wires about 15 inches. Do search of OBX

i believe sedans will not have any problems... but coupes have to relocate the driver side o2 sensor

its an estimated 18 hp gain so you would hope so

so can the stock o2 sensors be taken off the stock manifold and put into the obx? i read something about universal sensors but i rather just use the stock one.... thanks for the help

one of my sensor holes had to be relocated and the harness had to be extended.

how much you guys think installation would be?? all i got is whats in my sig and a cat coming in... so im guessing i need a custom b pipe and get the cat installed in my straight pipe. just making sure i dont get ripped off. this is going into the ka7

figure on 10 hours. That should round out to between 6 and 800 dollars.

Also, the OBX headers gained 13 hp and 10 tq on my 6 speed coupe with straightpipe, 2.5 inch b-pipe and 2.5 inch exhaust (cat-back is stromung).

The gentleman who dynoed my car worked as a mechanic for Jackson racing for 20 years, has his own performance shop now, and is of the opinion that most, if not all, of the gain came from the straight pipe.

I'd advise anyone who really wants performance to wait for the one we are developing:
New headers being developed
