I get a 4” or 5” exhaust?
truck is currently less than 500 RWHP, then upgrading to a
5 inch exhaust will actually cause your truck to lose power
on the low end of the turbo spool. The speed at which a trucks
turbo can spool is directly related to the amount of backpressure
on the exhaust side of the turbo. By going with a larger exhaust
system, it takes more backpressure and more time to reach
the amount of turbo spool that you were able to reach before.
Therefore, we recommend 4 inch systems, unless, you are( or
plan to be) over 500 RWHP, or if you prefer the sound of a
5 inch system.
I Choose an Aluminized or Stainless Exhaust System?
system from the factory is aluminized steel. With the aluminized
system you will get the same performance as a stainless system.
However, the aluminized system is more susceptible to rust
and usually has a lesser warranty from most manufacturers.
Our general rule is to recommend stainless to any customer
living in an area that usually receives snow fall during winter
months. This is because the salt on the roads quickly promotes
corrosion and rust on the aluminized systems.
is There Rust on My Stainless Steel Exhaust System?
a common belief that stainless steel cannot rust. This is
false. There is only one grade of stainless steel that cannot
rust and that is surgical grade stainless steel. All other
grades will contain some iron content to prove rigidity in
the material therefore they can rust to some degree. Purchasing
a stainless steel exhaust system prevents the system from
rusting though, as mentioned above the system may develop
some surface rust. That rust should not, however, cause any
harm to the exhaust system or its ability to function.
is a DPF?
for Diesel Particulate Filter. In late 2007 the EPA released
a new Standard of Emission Complacence rules for diesel trucks.
All light duty diesel pickups manufactured after 07.5 and
up now come equipped with a diesel particulate filter in line
with the exhaust system. The DPF is a two part system, a physical
filter and electronic sensors. The filter portion of the system
catches an extremely large percentage of the particulate matter
which leaves the exhaust, and when the filter is full, the
sensor portion kicks the truck into what is known as a regeneration
cycle. During this regeneration cycle the filter goes through
a phase in which it burns all of the particulate matter. While
in this cycle most trucks lose a considerable amount of power
along with huge drops in their fuel economy.
Truck is a Long Bed. Why Isn’t There an Exhaust Listed
systems are universal for bed length. This means that each
exhaust is made to fit the longest truck produced for that
particular make and model. This also means that you might
be required to cut one of the pipes on a shorter truck. (see:
Can I Install An Exhaust Myself?)
I Get a Turbo Back or a Cat Back Exhaust System?
back exhaust system will provide better air flow and lower
EGT’s than a catalytic convert back system will. The
down fall is that most Turbo Back Systems will eliminate the
catalytic converter. This usually doesn’t become an
issue unless you live in a state that requires emissions testing.
Removing the catalytic converter does not usually cause a
truck to fail the emissions smog testing. However, it will
cause the vehicle to fail the physical inspection. Therefore
you should asses the risk of failing an emission test. If
the risk is high then you should choose a Cat Back system.
If emissions regulations are more relaxed in your area then
you can choose a turbo back system. Your local DMV should
be able to provide you with information on the emission regulations
in your area.
I Install the Exhaust Myself?
In the grand scheme of diesel related upgrades, installing
an exhaust system is probably one of the easiest things you
can do. All of our exhaust kits utilize the stock exhaust
hangers; therefore,everything pretty much goes right back
in where the original exhaust comes out. Unless you are attempting
to save the stock exhaust system, it is very helpful to have
a sawzall to cut the pipe which often makes removal much easier.
Brand of Exhaust Should I Choose?
choosing an exhaust brand you should consider 3 things.
gains are practically the same between all of the brands that
we carry therefore to ensure your satisfaction with your purchase
you should choose based on the style you want and how much
you are willing to pay for it.
a New Exhaust System Improve my Horse Power?
any upgraded exhaust system should increase horse power on
a stock truck. However, the increases are small and may not
consistently show up on a dynometer test. Overall, you should
be able to feel a noticeable difference in power by upgrading
your exhaust due to the increased airflow.
is the Difference in Sound if I Add a New Exhaust System?
to a new exhaust system will ALWAYS make your truck louder
than it was at stock. The difference in sound is the result
of two different variables. First, how big the diameter of
the exhaust is. The greater the pipe diameter then the louder
that exhaust will be. The second variable is the muffler.
A more restrictive muffler will obviously reduce the sound.
is a Cat Back Exhaust System?
Back system refers to an exhaust system that begins after
the catalytic converter and continues to the tail pipe. This
type of system is very popular in states with strict emissions
regulations, because it does not remove the catalytic converter.
Kind of Clamp Styles Do the Exhaust Kits Use?
kits typically use two main styles of clamps. V Clamps, which
attach the exhaust system to the turbo and band clamps for
Doesn’t the Exhaust I Want Come With a Tip?
systems are typically sold as a full kit from the manufacturer.
Therefore if the kit in question does not include an exhaust
tip, it is because the manufacturer chose not to include one.
However tips can be purchased separately and will work with
almost any exhaust system.
