I applaud you for wanting to keep your car stock, and if you are driving it as little as you claim to be each year, then it will likely be fine. But if you plan on driving it in traffic on a summer day, I would strongly urge any FD owner to replace the pre-cat with a downpipe and change the radiator to something bigger than a notebook...

As far as I know (and I dont know much, so feel free to correct me) the stock pre-cat was designed to aide in heating up the exhaust system to get the main cat hot as soon as possible, so it could actually...well...convert things. So any device designed to retain heat cant be a good thing.

I can tell you my car would run between 95 and 110 degrees before I removed all the junk keeping heat in the engine/engine bay and replaced the Rad, and now it runs at a stable 87 degrees.

I am sure you know what you are talking about (probably know more than I do) but from everything I have read, heard accounts of, and experience first hand, there is no reason to keep the stock pre-cat on the car, and every reason to replace it with a downpipe.
