On a tier four Cummins in a dodge, the def system allows for less fuel usage for exhaust after treatment.
It measures the amount of oxygen in the exhaust stream. The computer uses that info to adjust the amount and timing of the fuel injection system to achieve the best emissions, power, and fuel economy.It measures the amount of oxygen in the exhaust stream.

The first symptom of an exhaust system problem is your vehicle will be louder than normal,especially when accelerting. You may also notice a drop in performnce and fuel economy.
Using a cat back exhaust system can benefit you because it will free up your exhaust gas flow and produce a more pronounced engine note. Installing a cat back exhaust system will also increase your fuel economy.
there should not be any fuel in the exhaust system, if there is, you have serious problems
High performance exhausts can have a small, yet statistically insignificant, impact on fuel efficiency. They tend to be installed for a differenct exhaust sound or improved power, not improved fuel mileage.
I noticed a nice gain in fuel economy by doing an intake system and exhaust system. One thing to note on these cars, is that they are computer controlled, every 30 miles the computer reprograms itself to optimize your fuel economy. I have seen from 33 up to 38 mpg with just the 2 above modifications.
Yes. In my exprience a cold air intake and an exhaust can increa fuel economy. It gives the motor more power so you step on the gas less. Also a modified fuel injection system with proper air mix ratio can increase economy but may decrease power.
A broken piston ring will allow fuel to enter the exhaust system. The fuel will drain out of the exhaust.
Unburned fuel in the exhaust system causes the backfire from the exhaust pipe.
