Exhaust Manifold Replacement wrong Options

[MonsterBOX]

i ordered an exhaust manifold from direct auto specifically for a 7afe 97 st at200 engine! and they sent me one but it has a hole for the o2 sensor insert and on the part it is labled 97 celica but on the recept it says something bout a geo metro or some ****...anywayz it looks like it will bolt up but i my 7afe doesnt use o2 in the mani only in the downpipe so anyone know how the plug this hole efficiently??? are there block off plates ne were available or should i install an o2 sensore but not hook it up...i got this mani cheap so i dont want to have to go and buy yoto oem

hrrrrmmmm
it sounds like you got a 94-95 OBDI manifold instead of the OBD2 manifold....(they came with the o2 sensor in the mani as opposed to the 96-99)....

the geo metro and such all share the 7afe motor with the celica so don't worry about that

first, there were no 98-99 ST Celicas, only until 97

The 94-95 manifold is VERY different than the 96-97 (because of newer emission regulations, like Dan said OBDI and II)

very easy way to tell is with the 94-95 manifold has a GIANT cat that bolts directly to it, then the exhaust pipe. Now the 96-97 has NO GIANT cat, just a pipe going strait down from the mani.

does you mani have a big mouth opening at the end, or just a small one for the exhaust pipe ?


I think you've got one for a 7afe for a metro or a prism. You need to specify for a Celica.

either way, just PM defgeph, he has a 97 ST manifold for sale. It is exactly what you need and it was only used for about a year I believe (he bought this one new from Toyota)
