    Default Heat shielding material

    I'd like to add some heat shielding to my floor to keep heat from the intermediate pipe from frying my foot. What have you used that you like? I'd like it to stick to the floor pan if possible. It's not legal to wrap the exhaust pipe in Spec Miata.

    What part of your foot... back of heel resting on floor, or side radiant?

    Any chance you have an exhaust leak?

    It will get hot down there, but it shouldn't be to the point of discomfort for your foot.

    I've heard good things about Lava Mat, never used it myself. The reflective aluminized fiberglass also seems to work well.

    It would go on the floor where it transitions to the transmission tunnel down by the gas pedal, where the mid pipe is located under the car. I don't have a leak, but I can feel the heat. I had a mid pipe without the factory shielding on it and it bloody well roasted my foot. I replaced it real quick with one that had the shielding.

    It's livable as is, but I'd like to see if I can make it better.

    I did this:

    It worked great. I took it out when I move the car from TTE to SM. Then my SM cage builder said it was legal in SM.
    I'll probably put it back in next time I change the transmission.

    Does the heat shield come with a crown, too? That looks like just the ticket. Thanks.

    Great stuff but HeatShield Product's HP Sticky Shield is FAR more effective:

    Not sure if it's better than HP Sticky shield, which has a fiberous insulation layer. If that muffler heat shield doesn't have a significant air gap behind it, it may not be any better, and if it touches the chassis, it can be much worse.

    I used the HP sticky shield on my RX7. On the tunnel and on the exhaust shield between the intake. Big difference! Not sure about the cabin temps other then it feels cooler. But under the hood 20 to 30 deg. cooler and I can put my hand on the tunnel after a race. When I could not before. That's checking the bottom of the air cleaner.

    I used this on my car. It works great. I put it on the underside of the tunnel, but make sure to degrease and clean the surface first. I would even suggest rattlecan painting the underside too in order to give the adhesive a clean surface to stick to.

    I have a coated JR header and it burned the paint closest to it's location in that transition. I cleaned and painted that inside.

    I used aluminum tape to seal the edges.

    I only watched this video on my phone but it sure looks like the "King" favored the wrong side when installing the heat shield. It looks like the shield ends well above the down pipe but plenty of shield over on the non-exhaust side.

    My feet got hot in my car after having the tunnel reshaped to fit a race seat. I had to reshape my Borla SM exhaust resonator to keep it from touching the tunnel. I tried some adhesive shielding but it didn't seem to help much.

    It's installed with an air gap, as the link states

    Yeah, I use this kind OEM heat shielding for many years and it works amazing with some airgap.
