So, I hunted again and cannot find the 2003-2005 Civic HYBRID free pdf that I trust is a safe download. I find pages and pages of shady or paid webpages, some of which I think will only offer on screen access for a short trial period. I would like to store the info on my device.

So I went to the Honda eStore site and got images of two CATs on the 2003 Civic Hybrid (attached).

2003 Civ Hybrid, first catalyst:


2003 Civ Hybrid, second catalyst (#7, lower left):


By contrast the site shows that the 2012 Civic HF had no second catalyst on the exhaust pipe. [EDIT: 2012 Insight & the CRZ had two CATs, with a sensor on the second one too; & 2017 Honda Fit 6-speed manual base also has a second CAT.]

That market would be, I think, California. And with it so simple, just a device without electronics, they could install it for Cali at minimal cost with simply exhaust production changes. Suggests we could use one and get some emissions benefit.

I will rebuild Black and Green over decades as parts die, until it becomes a different car of roughly the same shape and color. My minimum fuel economy goal is 55 mpg while averaging posted speed limits. I generally top 60 mpg. See also my Honda manual transmission specs thread.
