my guess is that coating those headers would've probably cost more than the headers themselves.
OP. do you plan on spraying the wrapped headers with the high temp sealant? From my understanding that's the norm when wrapping headers.

From what i understand is that when you heat wrap you header, the expansion and contraction between the pipes and flanges become more uneven. Over time, this will cause the welds to fail.

Heat wrapping is a bad idea on stainless, it speeds up corrosion and can cause premature damage (cracks, etc) due to un-even heat stress on the metal.
Jet-hot coating is usually about $100 per header for something that size, and well worth it.
Or, they're stainless, leave them be.

I'd had experience with the same manufacturer, now being sold as "AMK" but they aren't. Its a company out of New Mexico. I dealt with them for my sr20 needs back in the day, same setup, no issues for 2 yrs until I sold the car and from what I hear of the new owner he had no issues (turbo mani's)
The heat sealant is next its on order, I don't like the pepboyz type but another type coming.
Overall cost of headers heat wrapped, sealed and installed then dyno'd will be less than the cost of any "expensive" headers on the market. cost to performance I was looking at, paying $600+ for headers is just weird if you ask me (unless they are supposed to super special and give huge gains).
Install pix, clearance and dyno chart to follow eventually....

What kind of wrap are those, looks interesting? It's true that with uneven wrap that the headers can crack since it'll create hot spots, but it's more of a combination of it with low grade alloy used on the headers. You can see a lot of race cars using heat wrap including the Nismo Fairlady 380RS. The thermal insulation capability of the wrap has been tested to be greater then ceramic coating. I've also wrapped, silicon coated, and silicon sealed my headers.
This is with the Tomei Wrap (much easier to use) and DEI's silicon sprays.

^it looks easier, the wrap I've used I have had experience with, even though it sucks and burns if you touch your skin with it it ultimately does the job correctly...

Some of my friends still have their muscle cars from high school that we used header wrap on with no problems. That's over 10 years on a vehicle that isn't daily driven.

I'm going to some Z meet in landsale (NE section) tomorrow morning gana dyno in the morning.
first dyno will be:
Test Pipes
TurboXS 3" straight exhaust (no cats just a muff)
Mishimoto c/f intake
dirty wheels...lol (thats neq hp)
untuned
After install dyno will be:
Test Pipes
TurboXS 3" straight exhaust (no cats just a muff)
Mishimoto c/f intake
Headers
5/16 iso spacer
rota wheels (woot ++ hp lol)
tuned and untuned....hopefully if I can find a shop
