Would it be worth heat wrapping my manifold before fitting it on to my car? I know the manifold is at the back of the engine but heat will still radiate plus if I boost it like I want to I'm sure this with produce a lot more heat!

Any opinions welcome and I'd be interested if you've heat wrapped yours and what type of heat wrap and amount it took :)

Its a good idea ...but some manifolds do not take kindly to heat wraps and the welds crack.

A turbo mani and and an exhaust mani are two different things.

I have my Tegiwa done with no issues

Exhaust Insulation 101
What it does:
Using an exhaust header wrap or our Heatshield Armor exhaust heat shield on your exhaust system will retain more heat inside the exhaust system. This results in two significant benefits: (1) Reduces the amount of radiant heat damage to other vehicle components and lowers under hood temperatures and (2) exhaust insulation will maintain hotter exhaust gases. Hotter exhaust gases have a decreased density; this allows the exhaust gas to exit the system faster. An increased exhaust scavenging effect is produced in some cases this can also lower intake temperatures: that all equals more horsepower!

FAQS:
Will wrapping my pipes damage my exhausts system? No-It isn’t really a question of the wrap causing damage, it is more an issue of the quality of the exhaust system. Exhaust wraps are water resistant; they won’t keep water on your exhaust system and cause it to rust, unless your pipes become completely soaked under water, it would be very difficult for the water to get to your pipe.
Header wrap, can help to prevent rapid heat and cooling in cold climates, and reduce cracking. If the exhaust system is made from a good quality steel, insulating it should not damage your system!

All fiberglass and volcanic rock wraps are water resistant by nature, they are not water proof. The only way they could possibly retain water on the exhaust pipe, is if there were to be completely submerged in water after they were installed. Test it on a piece before installing, spray one side of some header wrap with water in a bottle, let it sit for a minute, turn it over and notice the other side is dry!

So definitely worth doing then! I've got either a toda manifold or Tracy sport so I hope they won't crack after being wrapped

I'm planning to supercharge my fd2 next month so I was concerned about the heat soak coming off the manifold even if it is at the back of the engine :)

I wrapped my old Tegiwa mani on my old dc2. Bit of a ball ache doing it but was a good job when it was finished and never had any problems.

With a non aftercooled Jackson you wont be worrying about heatsoak from the manifold lol
