I have a 2000 Insight with about 100k miles on it. The 90k service was performed a few months ago. A few days ago my CIL came on, so i took it in to my dealer. They said that the cat was bad/used up (understandable at 100k miles) and has to be replaced.

They quoted me $1,300 for the new cat and $300 instalation!? $1,600 dollars for a new cat!? Come on... I bought the card used for $6000.

I was wondering, first, if anyone else knows if this is the normal cost for a cat for an Insight? It seems WAY high considering a new cat for a Chevy is $100. And secondly, is there any reason I couldn't buy a $80 Cat from SummitRacing and weld it in place myself? Maintaining, of course, both O2 sensors.

Thanks.

Just had mine replaced at 105K miles cost was $1100.00 parts and $200 labor. That was a pretty good price for the CAT replacement. Seems hard to believe, huh?

Hi DVDempire; Yes, $1600 total is too much. However, it is nothing like a CAT for a Chevy. This is a special lean-burn capable CAT, with a platinum storage surface (fairly high tech for production cars) Along with platinum, there is also small quantites of Rhodium and Tritium. One of the oxygen sensors, the linear one, is also expensive. It has the ability to sense air/fuel ratios as high as 24 to 1. My suggestion is to shop around and find a new CAT for about $950, or a used one for alot less. Billy.......

haprecycling.com has one for $250, but it has 97,000 miles on it. Could last a while longer.

Sorry to nit-pick Billy but last time I checked Tritium is a radioactive gas :shock: Don't think there's anything radioactive in there :!: ;)

The NOx converter has a Ti-Na coating (Titanium-Soduim). Both are coated on a very fine mesh ceramic substrait wthl 600 cells per in2. And require very high temperatures to operate.

HTH! :)

I had asked in the hot air mod thread if sucking too much heat off the cat might hurt it, and I don't recall anyone replying specifically about that (not that I am faulting you for it! :lol: ), but do you think it is possible? Like if a fully enclosed heating chamber around the cat collected heat for the intake?

Sorry, please feel free to quote me and post back in that thread!

Its possible. Just don't think you can "do" it without a lot of extra trouble.

Too cold and a PO420 _will_ set. Can't imagine any CAT damage as a result. But you'd have to "un-do" the mod.

But if you calculate the SCFM if a 1 liter @2000 RPM the intake "flow" isn't huge. And once this "heat" is on the outer surface of the CAT it's "wasted" anyways.

HTH! :)
