does anyone know if 96-97 camaro y pipe and dual cats will fit on a 94 z28s stock manifolds ?

 

no cause the 96-97 lt1 has the big cat on the driver side right where the manifold to y pipe connection and the 93-95 dont have that.

 

You got it backwards 93-94 some 95's i believe have the big cat and the 95 or 96 & 97 have the daul cats

 

and the big cat is under the passenger side

 

the late model 95's that are obd2 have the big cat and its on the drivers side. it looks like a Folgers coffee can. lol. right where the exhaust manifold meets the y pipe. passenger side has the regular sized cat under the passenger

 

you are correct my freind...

 

Correct. The flange on the driver's side is different because it mounts right to the cat. Passenger cat is under the car.

 

There were no 95 OBD2 cars. The 95 cars that have dual cats were built to be sold in CA.
