LS header heat shield

[badazz81z28]

Looking for ideas....anyone have a heat shield of some sort on their LS headers?

What is the purpose? Stop heat in your engine bay or away from the starter?

I am also interested in this. I am more looking at a shield to keep the header heat off the firewall, toe board, and floor under the seats. On long drives in hot temps, or extended autocross runs in a row- I feel the heat a bit in my feet. Especially my heel at times. There are a ton of products out there for inside the car. But I have always wondered if a shield or adhesive backed metal attached to the bottom of the floor and toe board would help.

Not for the headers but for the floors and tunnel.

Thanks Donny. Have you used this before? Just looking for you thoughts on its effectiveness an installation process.

It's easy to install if it is the first thing you install. It's a bear to get in the tunnel of a car with a drivetrain in it.

Make sure everything is clean. CLEAN. or the adhesive won't stick. When it does stick, its stuck, plan ahead. It is easier to cut a pattern from cardboard and fit that to the car and then transfer to Floor and Tunnel shield. Good shears are required to cut the stuff. It will not do compound curves with out relief cuts.

After that, enjoy your new, cooler floor. We did a 69 a while back that sees alot of autox and track time. The leaking T56 shifters have put oil all over the stuff and it is still stuck 4 years later.

I've done the same thing and it helps tremendously with heat and sound. I would also suggest you wrap your headers in DEI Exhaust wrap https://www.amazon.com/010127-Titanium-Exhaust-Heat-Technology/dp/B0039Z5TIG?th=1

Header wrap I don't much care for. Ever see the wick in an oil burning lamp? :)

[badazz81z28]

This what what I'm protecting...I didn't want to put it here....but I'm trying to work with it.

dont wrap your headers. Put a cover over it and some of the heat product inside the cover. Simple.

That or mount the ecu on the inner fender.

I have had a Ford ECM about that close to a turbo. I did an aluminum heat shield and did not have issues but I am sure it shortened the life of the ECM.

[badazz81z28]

Yeah I know it's gonna get hot under the hood, I want to protect from radiant heat

With all the header heat why did you not put it inside of the car? looks like wire was long enough.

Because there is nowhere to put it, I had my 411 ECM sitting on my passenger floor for 2 years. I'm not doing that again. Additionally, I would have had to cut a good size hole to push the ECM connectors through. It's not the end of the world that location is exactly where the factory put it on my RAM as I'm sure many other vehicles out there. It's not uncommon and most ecms are in engine bays
