Default Up-pipe wrap - worth it or not?

So I just got my new catted downpipe to install before my tune on the 24th, and was going to go ahead and wrap it today.

This got me thinking, I see a lot of people that wrap their headers and uppipe, and I'm familiar with the pros/cons of wrapping things, so I might as well do that as well. Except, everywhere I look it states that removing the uppipe is a massive, massive pain.

If I'm already going to be removing the downpipe to swap that out, how much trouble is it to do the uppipe and headers at the same time? There's already an aftermarket uppipe, so no cat. The car just got back a month ago from the shop for a full engine replacement, so I don't expect to run into any stuck bolts.

It takes like 10 minutes to wrap headers and uppipe. If it's coming off already you may as well do it.

The only reason that they'd come off is to get wrapped - that's the part I'm unsure of, if wrapping the up pipe is worth the trouble of removing it.

i dont think its worth taking them off just to wrap it. i wrapped mine so it doesnt burn up my axle boots and other stuff near it before i installed it, so have no comparison to not wrapped.

Turns out, after doing the downpipe I wouldn't have enough wrap to do the headers anyways, just the uppipe, so I'll probably hold off on doing those until I go to equal length/different turbo. Or until I run out of other projects, get bored, and order some 1" DEI next-day from amazon.

I'm finishing out a 2"x50' roll now. Did my '04 Miata headers and '88 TT 600 exhaust when I refinished the exhaust on there. The bike exhaust came out pretty well imo, but I really wish I'd gotten the 1" stuff, and probably won't ever buy the 2" again.

I really ought to cover my turbo, any how-tos for making a cover with the heat wrap?

Do you still have the original catted up pipe on the car? If so it'd be worth it to swap to uncatted which obviously you can wrap before install.

No, as stated it's already got a catless uppipe, can't remember which brand though. Ebay, same as everything else the PO did to the car. I have enough wrap left after the DP to the UP, but not the headers, so I'll probably hold off and take care of it whenever I change out another major component like the turbo or headers.

If you do it right, this is not a 10 minute job, ever. Especially not on a Subaru manifold.

I'm not gonna bother voting, but if you're just talking about the uppipe, you have nothing to gain. If you're talking about a full tubular manifold w/o heat shield - you NEED to wrap it to retain heat.

i wouldn't take it out just to wrap it. i have my turbo, headers, DP wrapped, all while on the car. only thing i don't have wrapped is the UP because i'm not taking it out just to wrap it! my temps stay pretty cool between the hot side of the turbo and DP being wrapped though.

agreed, not a 10 min job if you expect it to last or be even a bit effective.

Dang, that looks really nice.

What's the foil heat wrap? I don't think I've seen that before. I'm not terrifically happy with my downpipe wrap job (only had 2in wrap left. It's serviceable, but not pretty) so I may re-do that whenever I do the headers and up with 1in. That foil wrap looks like it would help a lot.

Thanks...labor of, well, fear of heatsoak. The foil is just heavy duty HVAC adhesive tape from the hardware store, 3M I think. I tied it over the foil with aircraft safety wire. Props to Ride5000 for the idea in his thread.

During oil changes, even after 30 min driving, within minutes you can touch the foil on the collectors without much trouble or burns. I don't run the OEM shields at all.

That's overkill, but nice work. Ideally you want two layers - heat wrap and a metal flame arresting layer. Only the wrap needs to be in thermal contact with the pipe.
