The exhaust and muffler on my FP car runs through the center tunnel on the car. This puts a lot of heat into the driver compartment throught the floor board. This is a tin top car.
I would like some advice and any recommendations on heat shield wraps or other method to keep the heat under the car and not in the drivers compartment with me. (no cutting the roof off is not an option lol)

Thanks

Are you still using the OE radiant shields? If not, reinstall them. It is pretty amazing how effective a simple piece of sheet metal can be...

I use DEI's "Floor & Tunnel Shield"
https://designengineering.com/products/ ... eflectors/

under the car, I have a couple layers. inside the car, I have another layer on the trans tunnel by my right leg and under all of my switchgear and etc mounted near the floor.

This is on the rotary with red-hot exhaust. before the shielding, the heat burned off the paint and turn the wiring that was touching the inside floor of the car black and crispy. after the shielding, it was hot to the touch, but I was able to touch it bare-handed after a race by the time I got to impound and dropped a glove down there..

I left the OEM tunnel shield in my car, but I added this type of stuff after it exits the tunnel to manage radiant heat off the pipe.

Dave, you might also look into ceramic coating the exhaust. I have done this on a number of cars and it is very effective. Basically it stops the heat from radiating off the surface. My RX7 is coated from header all he way back.
