I'm a little worried, I hope it's a case of me being stooopid.
The cat that you guys have taken the warm air mod from appears from the pics to be on the downpipe before the exhaust goes under the car. i.e on the vertical section immediately after the manifold.
I've just been out the my Insight & there's no cat there, just a plain downpipe with a brace bat back to the engine.
Please tell me I'm misunderstanding things.
