Cat-backs and CAI should have a vary-vary small increase in gas mileage. Like maybe ¼ mpg. All the 3 and 4 MPG claims are bull. Now the people making that claim probable believe they got this gain but variations in driving style has the biggest impact on mpg.

Donnie – The testing I’ve done for TundaHeadquarters.com shows that most exhaust systems have minimal impact on fuel economy. If you’re trying to boost gas mileage, you might look at a cold air intake system first. However, if you’ve got the money, adding a quality cat-back exhaust system can add a few hp and improve mileage. Reply

On to the exhaust & fuel economy: a motor is a pump, and anything that you do to increase the volume through the pump will increase the power output. If you consider that the motor is pumping more all the time, you will understand that economy will suffer across the board.

the reason bigger pipes hurt lowend power is exhaust volume. if there is more volume in a pipe and the same amount of gas going through it, that gas is no moving slower, thus cooling more, and moving even slower. yes big pipes give you massive upper range gains, but at the expense of the range where you spend 99% of your RPMs.

A cat-back exhaust system replaces your OEM system from the catalytic converters and back. The pipes are larger. The mufflers are also designed to facilitate a more efficient draining of the exhaust. Cat-back exhaust systems improve gas mileage and enhance engine sound as well.

An increase in fuel economy is often experienced after installing a cat back exhaust system. This is the result of the engine not have to work as hard pushing exhaust gases through the piping. This reduces the total amount of load on the engine, causing higher efficiency and MPG. This increase in fuel economy typically occurs when traveling at freeway speeds, but can sometimes be noticed when driving in the city as well. Another big benefit of a cat back exhaust system is the sound they can ...

The cat-back system frees the restriction of gases, reducing the engine's work load and improving gas mileage. The free flowing gases flow unrestricted and the engine is able to produce more horsepower and torque as it is easier to push the gases through the exhaust. Keep in mind, some back pressure is necessary for peak performance.

As the name implies, a cat-back replaces the factory pipes from the catalytic converter(s) back. It features larger-diameter pipes and free-flowing mufflers to better scavenge exhaust gas from the engine. Better exhaust scavenging lets the engine pull a fresh air/fuel charge into the cylinder heads more quickly, which improves both power and mileage.
