Hello. I need help identifying an exhaust manifold/downpipe on a 1997 RHD Accord Wagon with f22b vtec engine.
I’m not sure if it came with this exhaust configuration or if it was changed to meet emissions when the car was imported.

The upper cast iron manifold seems to match 94-97 accord.
But...
This downpipe section
1. bolts to the back of the engine.
2. Has the o2 sensor on top just behind that engine mount.
3. 3 bolt exit flange. Triangle is slightly offset on first flange.
4. hanger comes up beside the flex pipe.

(The catalytic converter also has the 3 bolts on each side and is identical in design to the 90-93 accord/92-96 prelude cat.)

The 97 Base model Prelude exhaust manifolds seem to be very similar, but the o2 sensor bung configuration is further back behind the flex pipe on those.

 

... is it giving you problems?
