Ford
Power Stroke 7.3 and 6.0 liter T-304 and T-409 Stainless Steel Single and
Dual Exhaust Systems
The MBRP XP and PRO exhaust systems,
offered by Diesel Performance Parts, Inc., are produced
using top quality mandrel bent T-304 and T-409
stainless steel exhaust components for the 1999-2003 7.3 Liter and the
2003 and newer 6.0 Liter, Super Duty trucks. Every system is shipped with
all the necessary parts and tubing to fit any body style or bed length
F250 or F350 pick-up truck, with the exception of the cab and chassis models.
The systems are designed to install on standard, Super and Crew Cab trucks
with both short and long beds.
The
systems begin at the turbocharger with the down pipe that is available
in either a three and one half or four-inch size for the 7.3 liter and
three and one half inch for the 6.0 liter. The down pipe is built from
T-304 or T-409 stainless steel mandrel bent tube. The
down pipe then joins with the four inch T-304 or T-409 stainless steel
tubing just before the transmission cross member on the 7.3 liter systems.
The 6.0 liter down pipe bolts directly up to the factory catalytic converter
two bolt flange. There is a catalytic converter test pipe available for
the 6.0 liter systems. Joining the two pipes just before the cross member
eliminates the need to remove the cross member for installation. It is
much easier to cut the factory system off when the system is designed to
install without having to remove the cross member. The 6.0 liter engines
also have the choice of a “CAT” back system for those that
don’t need the extra exhaust gas temperature reduction that the turbo
back systems offer. The four-inch section joins with the spiral flow core
muffler just before the rear axle.
 The
Spiral Flow louvered muffler is a six-inch diameter by thirty-inch long,
polished stainless steel case, containing an inner packing material made
of stainless steel wool, with a ceramic blanket outer packing material.
The interior of the muffler is a four-inch stainless steel tube that dampens
the resonance of diesel exhaust and still keeps the interior noise level
of the cab within comfortable levels of the factory sound level. The muffler
incorporates a Spiral Flow louver that is specifically designed for diesel
exhaust performance. Notice too the size of the louvers is small to eliminate
any restriction, but large enough to dampen exhaust noise. Some competitive
louvered mufflers use extremely large louvers that are a major restriction
in exhaust flow. The spiral pattern (view
picture)
of the louvers promotes the same flow the turbocharger introduced to the
exhaust gasses as they left the turbocharger. The spiral pattern of the
louvers helps speed the exhaust gasses out of the exhaust system to lower
the exhaust gas temperatures as quickly as possible. The competitions diesel
muffler, in a lot of cases, is a hollow core/can without any packing material
that actually produces a restriction by allowing the hot exhaust gasses
to get into the outer “can” and then trying to “fight”
their way back out of the outer can into the main exhaust stream. That
is the exact opposite of the reason you are looking for a performance exhaust
systems in the first place.
 The
four-inch tailpipe slides on the spiral flow core muffler and ends with
the optionally available five-inch tip(s). Dual wall tips are standard
on all T-304 single and dual systems. The systems we offer do NOT
have a TWO piece tail pipe design. Not only is a two piece
design more prone to corrosion and moving out of alignment as the system
ages, it’s has an unattractive clamp joint that is readily visible
on all four wheel drive applications. A tail pipe made out of a single
piece of stainless steel is exactly how the OEM manufacturer designed your
factory system and it is the best most secure and attractive way to build
a performance system as well. Diesel Performance Parts, Inc.
offers tips that are available in five-inch T-304 stainless
steel as either a straight cut or angle cut single wall rolled edge or
as a dual wall straight cut or angle cut edge designs. 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. Final positioning of the five-inch T-304
stainless steel polished, rolled edge tip and tail pipe is accomplished
using the adjustment provided in the rear muffler hanger bracket (view
picture). The joint clamps provided in our systems are plated to prevent
corrosion and provide a long life. You can’t use a stainless steel
joint clamp as the threads of the stainless fasteners will “gall
up” when tightened sufficiently to seal the joints.
The systems are available in both single four-inch systems and also the
Dual four-inch systems for the ultimate in diesel exhaust
systems. The Dual systems have both a left and right side
tail pipe exiting at a sweeping angle behind both rear wheels. The Dual
T-304 systems come standard with dual wall T-304 tips for both the left
and right side tail pipes. Tips are optional for all T-409 systems.
The Power Stroke exhaust system has been dyno tested to produce as much
as 23-horsepower and 48-foot pounds of torque. The average gains are 18-horsepower
and 40-foot pounds of torque. The turbocharger spool up times are also
dramatically reduced. Mileage gains will be related to your driving style
and trucks operating condition. The extra power an exhaust system provides
is great, but the systems ability to lower your exhaust gas temperatures
will allow you to make other performance modifications and still keep your
exhaust gas temperatures at a safe level.
The
T-304 stainless steel systems are protected by an exclusive
Limited Life Time Warranty to the original purchaser. The T-409
stainless steel systems are protected by a 5 year warranty.
