Are the emission and O2 sensor connections the same on the 94-95 single cat headers and the 96-97 dual cat? thinking about bolting my old headers off my 97 Z to a 95 TA. Other than fabbing a y pipe, it should be the same right?

 

Don't know about ALL 97 headers, but there shouldn't be any difference. Each has a single O2 in each collector. The difference is in the Y-pipe.

 

Just looking at the manifolds on the TA, i thought so, but wanted to confirm. The design of the driver header should be different to accommodate the second cat on the obd2, but as long as all the connections are there, it should be okay. Can anyone confirm?

 

If they are shorties, would the drivers side header not have the really big 'dual cat' flange on it for the 96-97 Y-pipe? '95 was still single cat except in Cali, wasn't it?

 

Also... the AIR tubes (if you are running them) have different thread sizes from 93-95 to 96-97

 

Damn. That's what I needed to know. Have to have all emissions due to county inspection laws.

 

yeah i converted from 97 style manifolds to 95 style headers... it wasnt bad, i have 1 of the air tubes (drivers side) if you want id sell it cheap.
