Yet another letdown

[TRAMPLINEMAN]

Pretty sad that the exhaust on a ‘14 only lasts 4 years. Even tho the price tag keeps rising, these trucks are becoming more and more pathetic as the years go on.

It's kinda hard to tell from the pic, but looks like (maybe) pipe slipped off ?? Some roadways I drive these days would shake the "Grin off Santa Clause"! Maybe you drive some of those roads, too...

 

[Bill Lins]

Looks more like it ROTTED off!

It did. It did not slip apart.

comrade - where about do you live? heavy road salt ? mag chloride etc? cheers!

 

[TCDiesel]

LINEMan, its the chloride used on MN/WI roads.

Remember were we pick up the other Guy Blaine for Lunch ( Bioclean systems) We have been washing the Coke road equipment for 30 years, back in 2008 Coke's trailer hinges started to corrode, making the Roll up Doors lockup in some cases half way open, Coke (Midwest bottling contacted the Maker Mickey Trailer mfg) and Mickey claimed it was us, well after $10s of thousands spent in investigating why it was found that the road chloride was corroding the hinge pin, Midwest and Mickey worked for years and spent millions in repairs and eventually drop the side roll up trailer. We filed a complaint with the MNDOT, MNDOT reply was go pound sand, MN drivers are so stupid the roads requires the chloride to be safe.

The only way to slow / stop it is continue under body washing during wintry conditions.

The stuff MN sprays on the roadways is 1 step away from corrosive aggressive Acids.

Urea (Def) and ammonia that quickly combines with carbon dioxide and carbon monoxide in the exhaust (and) in the H2O (that is also a product of combustion and 68% of DEF) to form ammonium carbonate and ammonium carbomate is a corrosive concoction that eats away steel... Even more resistant alloys like stainless steel.

So the exhaust systems which are very complicated and expensive will need replaced more often than previous gens because they rot from both the inside and the outside as they are heated up. DEF and It's by products will rot it from the inside. Unlike previous truck systems.

Almost makes me wonder what they saw when they replaced my SCR catalytic converter a year and a half ago...... after 3 1/2 years of service (in terms of internal rot.)

 

[Ozymandias]

Newsa the Def Exhaust is stainless Steel.
Exactly for that reason.

....at least on European vehicles/truck.
couldn't lay under a def Ram yet.

Todd, I completely agree. I wash the undercarriage of the truck every weekend during the winter months. I actually put on rain gear and lay down at the car wash to get as much as possible.

And, I’m still going to bring you my truck. I’m busy every weekend from now till the end of November, but hopefully the beginning of December I can get it to you.

When the time comes to completely replace the exhaust, it will be replaced without all that garbage. I paid for it once, I will not pay for it again.

Many exhaust components have some stainless steel in them.

Even gasses and passenger cars.

It's just not necessarily shined up and polished like the stainless in some kitchen appliances. It is an alloy that resists corrosion. But is not completely resistant in the presence of corrosive chemicals (strong oxidizers) and heat.

They either are stainless or they're not. Most stainless exhaust components are lifetime warranty.

Awesome, If its nice I will wash the under body and engine at the shop , it will look new when I'm done. Just like mine at 5.5 years old.

I doubt these DEF (downstream) exhaust systems will last very long. But I hope they last a lifetime.

Most automotive exhausts don't contain much more than 10-20% SS. Depending on grade the steel can be a mixture of carbon, nickel, aluminum, manganese, aNd chromium. 304 has been found to corrode fairly quick in scr equipped trucks due to urea decomposition and high temps. I don't know what is used on these trucks.

I've noticed my 14 rusting in that exact same spot. I thought it was strange considering the rest of the exhaust is clean. Looks like a closer inspection is in order!

I only see a round of rust at the DPF outlet. It looks like it is starting to corrode there (from the inside) like the above picture.

The joint to the tailpipe looks good at first look

 

[TCDiesel]

It corroded form the outside due to the reaction of two different metals Pipe/Clamp when acidic liquids are heated with other liquids (Water)

Have you checked to see if this is covered by the emissions warranty?

For 2014 RAM:


A. Parts Covered for 5 Years or 50,000 Miles,
Whichever Occurs First
Diesel equipped heavy duty trucks are 2500 and 3500
models only.
Federal law requires Chrysler to warrant the following
emissions parts for 5 years or 50,000 miles, whichever
occurs first. • Air system controls; • charge air cooler and associated plumbing;
• coolant temperature sensor; • DEF system (includes tank, sensors, valves, pump,
doser, control module and heater);
• engine speed, position sensor, and cam position sensor • exhaust system (includes catalysts and sensors); • electronic fuel injection system, including injector; • exhaust manifold; • exhaust gas recirculation valve and control system
(includes EGR cooler);
• exhaust pipes (between exhaust manifold and last
catalyst);
• fuel pump, fuel lines and fuel injectors; • intake manifold; • on-board diagnostic-system components;
EMISSION WARRANTIES REQUIRED BY LAW
20
• NOx sensors, Ammonia Sensor and associated modules;
• positive crankcase-ventilation (PCV) valve or orifice;
• powertrain control module;
• transmission-control module;
• turbocharger and turbocharger speed sensor;
• turbocharger compressor inlet air temperature/
pressure sensor; and
• wiring harness circuits connected at both ends to
emissions warrantable components.
B. Parts Covered for 8 Years or 80,000 Miles,
Whichever Occurs First
If your truck has one of the following parts, this Federal
Emission Warranty covers that part for a period of 8
years or 80,000 miles, whichever occurs first, calculated
from the start date of the Basic Limited Warranty as set
forth in Section 2.1(E). The covered parts are:
• all catalysts
• powertrain control module
• transmission control module

I didn’t even check. I cut all the corroded parts out and sanded it all clean. I welded a short piece of 4” pipe solid to the tail section of pipe. I then tacked it in 4 places to the forward pipe. I covered the joint with a 4” band clamp.
