I have someone interested in my OEM exhaust. I need to know if it will fit his car. 1. Is there an O2 sensor right at the cat for 1995? 2. Is there an O2 sensor in the mid-pipe?

 

selling the '99 exhaust to a '95-'96 they will need a O2
plug for the stock B-pipe. The '95-'96 rear O2 sensor is in the catalytic converter so there will be a extra hole.


I have a '98 GReddy on my '95 and I got a O2 sensor plug from the local muffler shop to fill the hole in the B-pipe.

 

My 1999 cali-spec catback will fit on the 1995 since I don't have a hole in the b-pipe =) Only 97-99 Fed. spec have an O2 in the b-pipe. My 1999 cali-spec cat will not work on the 1995 because I don't have an O2 hole in the cat.

On a side note: Jeff..what's the exhaust difference between 95-96 fed. spec and 95-96 cali-spec? Is it the same, because the person that's buying my exhaust might have a 1995 fed.spec. Is there such of thing as Cali-spec 97-98? I haven't heard anyone mention this?
