You need to do some investigating. You need to know which one is not hooked up.

 

should be getting a code for the one that isn't there..... they may have just plugged the rear O2 sensor into the front sensor connector.....

 

Thats exactly what I think

 

anybody know if a 95 ram has the post cat o2 sensor? I saw somewhere that they may not. Just want to verify. Also most people recommend the hi-flow cat versus gutting it so that you maintain at least some back pressure...Anybody care to vote? gut or replace with hiflow? If I get a majority rule here, that's what I'll go with. Would like at least 5 posts! Thanks guys!

 

95 only has the pre cat o2. And I'd put a high flow cat.

 

im not as experienced as these other guys. However i have a gutted cat, and im replacing it with a high flow in about a week or two. Id say get the high flow

 

I've been leaning toward high flow and u guys are backing that up so great! I'm gonna get on ebay abd try to find a cheap one.
