The
Diesel Performance Parts General Motors Duramax system is manufactured to replace
the original equipment exhaust system components from the turbocharger down
pipe to the tailpipe assembly on any 2001 and newer Duramax equipped pick up.
Diesel Performance Parts Duramax system is a complete four inch mandrel bent
T-304 or T-409 stainless steel system that includes our spiral flow core muffler
and five inch T-304 polished stainless steel, rolled edge tip. The system has
been designed to accommodate any of the various cab and bed length designs currently
produced by General Motors. |
|
|
|
|
The Diesel
Performance Parts system begins with increasing the tubing size to four inches
by using the same style of factory flange and using the factory hardware to
ensure an easy installation of the system. The intermediate pipe has a welded
T-304 stainless steel hanger that guarantees a correctly aligned installation.
Depending on your trucks bed and body style there will be a short intermediate
pipe used that is ready for installation just prior to the spiral flow muffler.

The
Diesel Performance Parts spiral flow muffler is six inches round by thirty inches
long containing an inner packing material made of stainless steel wool, with
a ceramic wool outer packing. The interior of the muffler is a four inch T-304
stainless steel tube that dampens the resonance of diesel exhaust and keeps
the interior noise level of the cab within three decibels of the original equipment
system. The four inch one piece inner T-304 stainless steel tube is made of
one solid piece of tubing, not multiple parts. The Diesel Performance Parts
muffler design uses a spiral flow core louver |
|
|
|
|
|
|
|
|
|
 |
|
|
|
|
 |
|
that is specifically
designed for diesel exhaust performance. The spiral twist of the louvers produces
the same flow pattern the turbocharger introduced to the exhaust gasses as
they left the turbocharger housing. This spiral pattern helps speed the exhaust
gasses out of the system to lowers the exhaust gas temperatures as quickly
as possible.
The tail pipe is a four
inch T-304 or T-409 stainless steel mandrel bent tube that provides the maximum
|
|
|
|
|
clearance
for the suspension and spare tire during installation. The Diesel Performance
Parts five inch, rolled edge, polished T-304 stainless steel tip is cut and
rolled to help eliminate diesel soot from collecting on your truck or trailer.
Systems that use a chrome-plated tip, unfortunately have a very short life.
The tip is located directly behind the rear wheel and is battered by road debris.
The road debris will cause rust almost immediately in a chrome-plated tip, but
not in a T-304 stainless tip. |

Whenever
possible T-304 stainless steel hangers are welded to the system tubing to ensure
an original equipment installation and appearance. Welding the hangers is the
accepted OEM mounting method and the most secure and permanent method of mounting.
Systems that use clamp on hangers are more difficult and time consuming to install
and generally do not hang on the truck as well. Those mild steel hangers can
rust and fail over a short period of time and the system will loosen up and
misalign itself. The clamps Diesel Performance Parts provides to seal |
|
|
|
|
|
the pipe joints in the
system are plated for long life against corrosion,
an are of the full saddle design. You can not use a stainless steel joint
clamp as the threads of the stainless fasteners will tend to “gall up” when
tightened sufficiently to seal the joints. Stainless steel tubing is extremely
hard and the joints will need to be clamped to a much higher torque value
than in a mild steel system.
The Diesel Performance
Parts Duramax system has been dyno tested to produce as much as 25 horsepower
and 39 foot pounds of torque. While at the same time lowering your exhaust
gas temperatures up to as much as 200 degrees, and spooling up your turbocharger
dramatically quicker. The horsepower and torque gains are extremely important
but the ability of an exhaust system to lower your exhaust gas temperatures
so you can add other performance improvements is of prime consideration for
your engine. There are also some mileage gains to be realized, based on your
driving style and location.
