Mysterious rear seat burning?
This has absolutely nothing to do with this thread. Are you shielding the rear seat backs against the intense heat coming from the washer fluid? Perhaps the piping hot battery?
I wouldn't bother doing any sort of heat shielding on the exhaust, it won't help this problem. I might scrape the sound deadening off of mine and replace with dynamat, maybe it's a different compound than the OEM stuff
And if it causes an instant inferno, I'll extinguish the fire and report the findings back here.

I don’t appreciate your funny talk.
Thanks anyway for all your incredible logic, conclusions and ideas to the tread. (to use dynamat?)
Humble, let me remind you that I was the first to notice the problem and created this thread.
The pictures show how I shielded the whole freaking rear seats including the back of the seats. The bottom of the seats has double layer of the same shield material. But I’m not showing it in the pictures.
I have no more burns.
The shield is both, noise and heat reflector, for those like me with a single exit full open exhaust, noise reduction is a must if you want to drive your car every day. It was actually a really good idea to cover the rear of the seats to reduce the noise coming from the trunk.
So for your understanding, the back of the seats shield is for noise reduction, the bottom (not show in pictures) is for heat reduction. (Our tread), so we might have an idea of how to install it.
You can use Dynamat of whatever brand you like it. I have no intention to throw $300 FOOSE dynamat of my cash in brand names when I can fix it for $20
Thanks to people like you critiquing everything is why some folks here doesn't like to show his knowledge or just stop doing it. There is always a clown trying to look for attention.
thanks for checking out Kamote24
I wish that everybody check its rear seats, come on guys do it this weekend, its a 30 sec. check, just pull up your bottom seat, there is nothing to brake, just give it a strong pull up it will come out easily than you image.

Have you even figured out what's causing the problem in the first place?
I'm not throwing out brand names for names' sake, I referred to Dynamat because I just happen to have a big roll of it sitting in storage. So to sum this all up, I'm glad you showed us pictures of what you did to reduce noise coming from the rear and not what you did for the "heat" issue. Also glad you find my talk funny.
For all anybody here knows so far, a 5x5" sheet of cotton fabric could stop the issue completely by separating the seat foam from the factory sound deadening and sealer.
I'll pull my seats out tomorrow and do the same testing Hiboost already did to see if I can even get that area warm to the touch.
No intentions of looking for attention. You're suggesting everybody wrap their back seats in heat shielding. I can understand sound deadening because of noise coming through the backs of the seats from the trunk area, but again, what's that got to do with this thread, whether you're the OP or not?

I would not use cotton since you are not deflecting the heat, still a lot of heat will pass to the foam. Foam burn and retreat in presence of heat, cotton ignite fire and stay there extending the fire area. Use a dual layer of fiber glass carpet aluminum shield it.
or if you have a rich dady like frankiago with rolls of chip Foose dynamat around the garage, go a buy a brandname product like:

Anyways, can you please let me know how it's getting hot? What's the heat source? Like I said earlier I'll take my seats out tomorrow and try to get the temps up. If I burn my hand on this area I owe you an apology. Either way I will take pictures of what is or is not there.

Same here. Stock exhaust (100% stock car... for now), 3400 miles on it.
I'm more and more convinced that it is NOT due to the exhaust heat. I will keep the rear seat off and check temperature during next days, but I think that area isn't hot enough to do this. Otherwise, before doing this, you should have the gas tank completely melted ...

Guys this has nothing to do with the exhaust. The exhaust does not even come near this area. There are dozens of other places on the car that the exhaust would affect before this one.
If you notice in the pictures, this seems to be happening where there is a body plug with some sealer smeared over it. Then the sound deadening is adhered over top the body plug and sealer, but the sound deadening does not cover the plug on the driver side. It appears to me that there seems to be some kind of chemical reaction burn going on here.
The exhaust is nowhere close to the area that's burning on your cars. The gas tank is RIGHT under that area, I mean like 1" away from the body.

If you read the first post,.....anyway......, short story:
I seated a heavy weight guy friend of mine in the back seat; I give him "a ride" to show him what an evo can do.
An hour later I smell it some weird smoky smell.
Weekend I took out the seats for inspection, and found the burn
I have seeing people here with and without aftermarket exhaust with the same issue. read the tread.
I really don't care how the problem is starting or coming from because I’m not a vehicle designer, I can speculate things but not have time to provide serious clues, so I keep my mouth shut.
I just try to advise my fellows how I fix the heat transmission to my seats: shield it, and wrap the exhaust, I’m using a copper dust wrap solution from term shield industries and now, I can basically touch with my hands the exhaust pipes without a burn.
In order to solve the problem Mitsubishi had to come with a different exhaust solution, or thicker shields around the pipes, or....is not my task.
