Downpipe wrap

[Linemonkey]

What wrap did you go with?

I actually ordered two rolls, just to be sure, but one was plenty. You soak it in a bucket of water, first, and it makes it more pliable. You get a good tight wrap that way too

A recommendation from experience wrapping many exhaust parts:

Use DEI titanium wrap. Easiest to use and lasts great. No need to apply wet or spray once installed.

What are the opinions here on wrapping catted downpipes? I see LOTS of mixed feedback elsewhere. Everything from "it will melt your cats from the inside out" to "wrapping and increasing heat improves cat efficiency and performance". I see "blankets" are also offered for cats, which presumably hold heat in as well.

Thoughts?

From the research I've personally done, I would NOT wrap cats. Especially on the ecoboost. When I was tuning my explorer, I was constantly going into "cat over-temp protection" even with pretty conservative fueling and boost.  Cats need to be hot to work, but excessive heat will destroy them, and one of the few ways for them to cool off it through their body.

Thanks for the feedback. Out of curiosity, were you going into cat over temp on the OE downpipes/cats, or did you have aftermarket?

COT is just a calculation the computer does to estimate the temperature of the cats based on how the engine is running (there is no real sensor), but to answer your question I'm on all factory parts.
