Exhaust Frost

Every winter I have this issue, I've seen other tacomas with this, but not all of them. Is it water in the gas or something else? I could extend my tailpipe, but even then it would probably not fix it. Any thoughts??

 

Condensation freezing

 

Too much maple syrup in the tank

 

Mines done it since day one.. i was worried the first time
I saw it. Then i saw most other tacos woth the same thing.. not sure why though.. because of where the tail pipe is placed?

 

It's odd how some tacomas don't have this issue though. I was parked beside another tacoma today in a parking lot and he had nothing on his truck and mine looked like this. Maybe Shell gas has a higher maple syrup content!

 

Does it happen on both sides? Looks like the buildup is BC that is a void where an eddy forms I think. And then the radiant heat from your exhaust is melting it. If it only happens on one side that's just condensation from the exhaust.

If you take your flaps off that might help cut it down.

 

No, only the one side with the exhaust. I might just extend the tailpipe and see if that helps, that or cut it off!

 

Looks like it's primarily a Canadian thing. I guess it's 'cause you guys are too "cool"

 

My 2012 does it. Its not cold enough here for it to breeze but i constantly have black shit on my rear quarter panel and it drives me insane. Next nice day i'm gonna climb under there with a hack saw and cut it back under the bed.

 

Maybe cut it on an angle toward the ground.

 

Water is one of the main byproducts of combustion. Don't worry it's not water in your gas.

 

Just gotta say OP, with no dis at all..but the offroad lights, plus the halos, plus the Toyota, plus the Trd logo....its way too much. Too busy.

For what it's worth.

 

It's not the water they're concerned with. It's that damn maple syrup that has been known to cause fuel injectors to clog up and diabetes too.

 

Water is the results of the catalytic converter, not the combustion process.The catalytic converter combines Carbon Monoxide ( CO ) with Unburned Hydrocarbons ( HC ) to produce Carbon Dioxide ( CO2 ) and Water ( H2O ).

That is why your exhaust drips water.

 

well good thing you don't have to drive it.

 

I hear that Exhaust Frost can be deadly



Kinda looks like a cool cousin of mine...

 

Excessive idling. Get in that truck and drive it.

 

Not true, my commute is all highway miles. It's just the overall design of the tailpipe. Funny thing is I see lots of tundras with the same frost buildup. I might try cutting the tailpipe back about a foot, add a coupler with some clamps, and direct it down a bit more. This picture isn't even that bad, Some days I've had 1/4" of ice buildup back there, I know its not a concern, it just looks bad.

 

I live north of you OP and I have the same problem. It's doesn't do anything, doesn't hurt anything and I don't worry about it at all. I've seen other cars/trucks with similar problems. There's nothing to worry about.

I do 95% highway driving with minimal idling.

 

Wrong.
