Huge amount of water for 3.5 Tailpipe? Is this normal?

Well I don't know about your truck but basically what comes out of every one else's tail pipe when it's running is H2O and CO2 the cat cleaned up most of the other stuff (water and carbon dioxide is what was left)

 

I understand that, but that just seemed yto be extremely excessive amounts to me. maybe its just these engines...

 

Perfectly normal for any idling vehicle.

 

Nope. You should see how much condensate a 90%+ condensing furnace makes. [2 heat exchangers so the secondary one one strips so much heat from the exhaust/combusted gas that the water or condensate ''falls out'' of the combusted fuel and requires draining. It is slightly acidic so plastic is used as any steel [or brass/copper/bronze] would be eaten away by the slightly corrosive liquid.

 

All of the above advice is good and correct. This is absolutely nothing to worry about.

Based on your pictures, you have a low spot between your muffler and exhaust tip. This spot - plus the muffler itself - will absolutely accumulate water vapor as it cools (condenses) before it exits the tail pipe. You might try loosening your clamps, adjust tilt angles, and see if you can eliminate that low spot. You could also drill a 1/4" weep hole..

Remember also: these trucks also have a predominant forward rake. So even on level ground, water vapor in the exhaust is always trying to flow "uphill".

While a proverbial sledgehammer cure to a small stationary insect, leveling and/or lifting the truck will eventually help.

Do not discount or disregard the direction and inclination of the places you park. It is still fairly early to be watering your lawn every day, but do not overlook the obvious such as your neighbor's sprinkler giving that part of your truck a shower every day.

 

Sounds like time for a part out or trade to me. Or you could use this on startup
