Anyone else have a LOT of interior heat from 5.0 exhaust?

Brett, what did you use on the inside of the car when you put the mat down?
I would have figured, it would've stopped the heat.
are your pipes touching or mabe to close to the floor?

Hmm, so maybe it is the catalytic converters getting hot.  I wonder if my smog pump isn't pumping enough air or maybe the sensors/diverters aren't sending the air to the right places....??  I've never heard of this problem with the mustang guys

Jerry, I used Fatmat.  It think it's an asphalt based product (i had 'the smell' for a couple days) and is foil backed.  I dropped 2 full layers from windshield to just in front of the rear seat (I will finish to the trunk eventually) and this is without the factory material; I have the carpet pad in as well.  Anyway, the Fatmat didn't really help much.  I can only assume my cats are getting overly hot and since there's nothing blocking that thermal radiation, it's getting soaked up by the floorboards and the being conducted into the cabin at which point the foil on the Fatmat is powerless....?

you should get a laser thermometer and check the temps of everything on both sides, including the floor inside and out. If it's getting that hot in your car that you can't touch something, I would be worried myself. you have a lot of wires running under the carpet. I would hate to see them, or anything else under there get heat damaged.
BTW, are the exhaust tips a million deg. also?

Haven't had tips since thee 5.0 swap, just turn downs before the axle, so, I'm not sure.  So, if I picked up a infrared thermometer, how do I know if the temps are extreme?

Do the cats have a shield on them??? If not, that's likely your problem...
