How to cure silicone coating for exhaust wrap? - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

Stomachbuzz · 01-02-2020, 10:17 PM

Wrapped my header. Wasn't initially intending to coat it with the hi-temp silicone, but the instructions heavily recommended it, so I bought a can.

I got the DEI brand. The instructions say to cure the sprayed object at 400F minimum.

Obviously my oven can heat to 400F, but my header won't fit in there, nor would I want this type of chemical curing in there.

What is the recommended way to cure with respect to exhaust wrap? Can I spray it, and then assume it will cure when the header is on the car? Might not reach 400F without a cat

You could always purchase a super cheap used stove and use it. then sell or trash it. Or possibly find a place which does curing and ask to use their facilities.

I dug through their website some more and found it hidden away in the FAQ section that you can cure it by putting it on the car.

Probably should have put that in the initial instructions.

Go for a drive

Your exhaust will be around 400° F (200° C) driving around , and alot hotter if you start giving it some beans.

Ended up going for the "cure on the car" method.

Was definitely prepared for a decent amount of smoke and some bad fumes. That's what I got!
Still throwing off some nauseous smells (noticeable when stopped) even after 20 minutes of highway driving. Yuck! I guess the solution is just to keep movin'

around the lambda, it will easily reach 600°C in few minutes, and that s just by idling during coldstart and drive lowspeed
i would assume the whole metal header will reach at least 400-450 C, since the wrap itself will help contain the heat

edit: sorry, didn t read well that you already did..
good then

I love the smell of toasting heat wrap! For a week people kept asking me why I smelled funny at work.

Yep, it smells like hot dogs.
