air intake systems and filters
are very good at getting air to your engine faster and more
efficiently. However, aFe realized that it is important to get
the air out as well. Just like anything else, the more you ingest,
the more you need to expel, otherwise things can get clogged
up. That is the reason why we offer exhaust systems to go along
with our air intake systems. It is a natural extension of our
efforts to enhance more info ...the science of airflow management
in performance vehicles. This is especially true in the diesel
motor which is simply a huge air pump. Since diesel engines
are a compression ignition engine and modern diesel-powered
vehicles are turbo charged, the more air you pump in, the more
power you generate. However, which turbo charged diesel, it
is very important to get the hot exhaust out or the Exhaust
Gas Temperature (EGT) rise to critical level that could damage
the turbo itself. Most OE manufacturers offer a restrictive
3 1/2" exhaust system which is fine for normal every day
city or highway driving. But you bought a diesel truck for its
towing or work capabilities, didn't you? If so, you want more
power to go up that grade towing your boat, trailer or tools.
Getting the air in will give you more power. Getting the air
out will give you more power. When you get more air in and out
at the same time, you get a lot more power. With the 4"
exhaust systems are mandrel bent aluminized steel which eliminates
the sharp bends and kinks that the factory stock exhaust systems
have. The aluminized steel resists corrosion as well as stainless
steel but is priced more economically. Our large 8" diameter
straight flow through mufflers do a good job of letting the
air out as well. You do have the option of turning the muffler
around for better flow or quieter ride. The 5" diameter
Exhaust tips finishes up the entire system for a nice throaty
sound and appearance enhancement. aFe entire systems comes with
adjustable clamps, muffler and sectional tubing for easy installation
whether you have a standard, extended or crew cab vehicle. (Exhaust
tips sold separately). The kits includes Turbo-Back, Cat-Back
