Downpipe wrap

On another forum someone mentioned wrapping their downpipes. I'm about to install catless pipes on mine, and I was curious if there's any merit to that. Beneficial or waste of time?

Might be worth it.. these cars are heat monsters! Coupled with the intercooler location, the IATs get up there.

Would be interesting to log and find out if it helps...

I have wrapped headers on previous cars... no real data to speak of if it helped or not.
 
After reading several articles, I think I may do it. I have OCD when it comes to this car! It doesn't cost much and it certainly can't hurt. Plus they'll look pretty sweet lol

I'd say that StealBlueSho is right that the front pipe could help a bit now that I think about how everything is laid out under the hood.
 
My pipes will be here in a couple days. I'm going to wrap them and post a few pics, (as long as they don't look like crap lol) if anyone is interested

I did it on my Focus ST as well as a turbo blanket. The fuel lines ran right above the turbo and when I swapped in a larger GTX I couldn't re-use the stock heat shield. I used DEIs wrap and it worked great. Wrap it as tight as you can and only have minimal overlap. Eliminate as many frayed ends as possible. I also used stainless steel zip ties on it.

I could pull into my garage onto my ramps immediately after doing some pulls and crawl under the car and place my hand on the downpipe and on the turbo. It was scary at first but it makes you realize how well it works. My only hesitation to use it again is I live in MN and they heavily salt everything here during the winter. I'm not sure if the wrap would hold the salt in and increase corrosion on the downpipes. Otherwise I would not hesitate to use it again.

That is good information.  Any particular brand you used, seems like it worked well. 
 
Well, I finally had time to wrap them. Also sprayed the pipes with high temp silicon spray. Should get them on the car this weekend

Nice...should also help dampen the slight rasp that the catless pipes have

I hope so. I'm not expecting much from the wrap, but I'll do anything I can to keep temps down. Plus they look cool lol

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?
