    Probably just cause it to crack quicker retaining heat.

    Good luck wrapping it without swearing and throwing it at a wall

    it wont reduce egt's if thats what you would be trying to achieve. it will stop everything around it from melting tho if additional other heatshielding is'nt fitted

    Wouldnt the manifold be more prone to cracking if it was heat wrapped. its made out of paperclips anyway...

    potentially less so.....

    rapid heat cool cycles on something as "expandy" as a stainless steel is what creates fatigue stress, so slower cycles may in fact help its life keeping it hot. but not excessively so...

    thats one of the benefits of ceramic coatings.. but they cost more to apply properly than the cost of the manifold in the first place.
