is the difference between T304 and T409 Stainless?
- T304 stainless steel will not oxidize or rust, it can however
develop a golden color when exposed to high heat over time.
T409 stainless steel has a fair amount of ferrous material in
it and can show surface oxidization after some time, especially
when exposed to road salt. This can be prevented by applying
a stainless steel cleanser using a scouring pad. If you are
concerned about long-term appearance, you should get the T304
system. If you are more concerned about the price, but want
something that is more durable than aluminized steel, then the
T409 system would be the system of choice.
IMPROVEMENTS CAN I EXPECT IN TORQUE, HP AND TEMPS?
- While performance gains vary depending on the vehicle you
can expect a gain of 5% to 10% in horsepower and torque. For
example, with a 2005 Chevrolet Silverado with a Duramax diesel
engine you will see a gain of 18 HP. and 28 ft/lbs measured
at the rear wheels. You can also expect a reduction in exhaust
gas temperature (EGT) by approx 200° F.
THERE A DIFFERENCE IN PERFORMANCE BETWEEN DUALS AND SINGLE EXHAUST
- The performance gains are the same for duals and single systems.
The duals offer a deeper more aggressive sound over the single
system. This is due to the extra tail pipe and the fact that
most dual systems have a slightly different muffler configuration
than the single systems.
WHAT DOES "OFF - ROAD" MEAN?
- An "Off-road" system is designed to deliver all
out power gains. These systems make no provisions to retain
the factory catalytic converter. Some jurisdictions do not allow
the removal of your vehicle's catalytic converter therefore
they can only be legally used off of the highways.
I BE ABLE TO KEEP MY SPARE TIRE IN PLACE IF I GET A "COOL
Generally, MBRP designs all of its systems to retain the factory
spare tire. The only exception to this is the "Cool Duals"
system for the Chev/GMC Colorado and Canyon (Part No. S5028AL,
S5028304, S5030AL, S5030304).
YOUR EXHAUST KITS INCLUDE ALL CLAMPS & INSTRUCTIONS?
- Our kits come complete with all the required hardware as
well as clear, easy to read instructions with lots of pictures
to help you work your way through your installation.
I HAVE TO WELD ANY COMPONENTS WHEN INSTALLING AN MBRP SYSTEM?
- None of our exhaust systems require any welding. In fact,
our systems can be installed using common hand tools.
YOUR SYSTEMS FIT TO A DUALLY TRUCK?
- All of our exhaust systems will fit dual rear wheel (dually)
trucks. We do recommend that tips be installed to extend the
exhaust and avoid any discoloration of your vehicle.
SIZE IS YOUR EXHAUST?
- For diesel vehicles we offer performance exhaust systems
in 4" and 5" diameter pipe. Due to fitment issues,
some of the diesel systems come with a 3.5" down pipe.
Our Performance Gas single systems use 3.5" tail pipes
while the Cool Dual" systems use 2.5" tail pipes.
The front pipes on the MBRP Sport Truck systems vary from
2.5" to 3.5" depending on the size of the factory
IS YOUR DOWN PIPE SIZE FOR THE FORD?
- There are a few different sizes for down pipes for Ford
trucks. For 94-97 trucks the pathway for the down pipe is
very restrictive. In fact, the factory down pipe for these
trucks are flat, approximately 1.5" in height. Our down
pipe is 3" in diameter. For the 99-03 model years with
the 7.3L Power Stroke diesel the down pipe is 4" and
the 03-06 model years with the 6.0L Power Stroke diesel the
down pipe is 3.5".
THIS SYSTEM FIT TO MY TRUCK BED SIZE?
- The majority of our diesel and many of our performance gas
systems are designed to fit all bed sizes and cab configurations.
GAUGE IS THE STEEL THAT MBRPinc USES?
- All of the pipes are made from 14 and 16ga. tubing.
THE DUAL EXHAUST FIT AROUND MY HITCH?
All of our diesel exhaust systems will fit with factory installed
trailer hitches as well as most aftermarket bolt on hitches.
You may run into interference problems if you have a fifth
wheel or gooseneck hitch installed. In that case we recommend
installing a single system.
MBRP MAKE AN EXHAUST FOR THE FORD F-450 OR F550?
We now offer a turbo back system for the 6.0L Ford F350/F450/F550.
We also sell both single and "Cool Duals" filter
back systems for the 6.4L Ford F350/F450.
THE MIRROR POLISHED DIESEL TIP INCLUDED?
- Tips are included with all of our 4" diesel
applications (except the Performance Series.) Tips are included
in all of our Performance Gas applications except the off-road
systems where the tail pipe is a turn down style for added
WHAT LOCATION DOES THE EXHAUST TAIL PIPE EXIT OUT ON THE TRUCK?
- All of our single exhaust systems, either for gas
or diesel exit behind the passenger side rear wheel. Our "Cool
Duals" for diesel trucks exit behind the rear wheels.
We offer you a choice for "Cool Duals" on your gas
powered trucks of either out the side exiting behind both
rear wheels or straight out the back on both sides.
MBRP MAKE EXHAUST SYSTEMS FOR THE CAB & CHASSIS TRUCKS?
- We now offer a turbo back system for the 6.0L Ford
F350/F450/F550 Cab and Chassis configuration.
EXHAUST TIP IS INCLUDED WITH MBRP EXHAUST SYSTEMS?
- Our 4" Pro Series diesel systems come complete
with dual walled angle tips. For the "Cool Duals"
they are the angled T5053 and the single has a straight cut
T5049. The XP and Installer Series have our T5051 angled rolled
end tips. Our Performance Gas, Muscle car and Jeep exhaust
have a variety of tip designs to suit the style and application.
In all cases the tips are mirror polished T-304 stainless
steel save for our Black series systems which have a coated
black tip. Our 5" diesel, Performance series and PLM
systems do not have a tip included nor do systems with a turn
YOU MAKE A TURBO DOWN PIPE FOR THE DURAMAX?
- In the fall of 2009 we introduced the GM8424 3"
down pipe for all LLY/LBZ/LMM Duramax engines coated in a
high heat black finish.
WAY SHOULD I INSTALL THE MUFFLER?
- The muffler on the single diesel exhaust systems
should be installed to allow the exhaust gasses to flow smoothly
over the louvers on the muffler core. If the muffler is installed
so that the louvers catch the exhaust gases it will increase
resonance levels inside the vehicle.
WARRANTIES DO I RECEIVE WITH MBRP EXHAUST?
- Pro Series (T-304 stainless steel) - Lifetime warranty.
XP Series (T-409 stainless steel) - Lifetime warranty. Installer
Series (Aluminized) - Three (3) years. Black Series - Three
(3) years for the components; One (1) year for the coating.
Performance and PLM Series - Two (2) years. Remember: You
MUST send your warranty card and a proof of purchase to MBRP
to activate your warranty. All warranties are from the date
SHOULD THE DUALS MUFFLER BE MOUNTED... VERTICAL / HORIZONTAL?
- It depends on the model of vehicle involved. The
systems for the Chev/GMC Duramax and the Ford Power Stroke
position the muffler outlets vertically. The systems for the
Dodge trucks with the Cummins motor have the muffler positioned
with the outlets horizontal.
I LEAVE THE CATALYTIC CONVERTER IN?
- Yes, the catalytic converter can be retained for
all current model trucks. Be sure you have purchased the correct
system that will allow you to retain the converter.
ARE THE DIMENSIONS OF THE MBRP TIPS?
- We have various sized tips from 2 1/2" to
6". All of our tips are available in mirror polished
T-304 stainless steel and many are now available in black.
ARE THE ADVANTAGES OF A MBRP EXHAUST COMPARED TO THE STOCK?
- By installing an MBRP exhaust system you will see
an increase in horsepower and torque. Fuel mileage gains may
be noticed as well as a decrease in exhaust gas temperatures
(EGTs). By lowering EGTs you will increase your turbo longevity.
WHAT STYLE OF MUFFLER IS USED?
- The muffler used on all of our diesel systems is a straight
flow through design with a spiral louver core. The muffler
is packed with stainless steel wool which is then wrapped
with a ceramic fiber blanket. This combination creates the
deep mellow exhaust note that MBRPinc. systems are known for.
Our Performance Gas systems use a variety of high flow muffler
designs utilizing the same spiral louver core design as our
diesel mufflers or tuned chamber designs specific to the application
MBRP COOL DUALS™ FIT TO MY TRUCK IF I HAVE GOOSE NECK
- We do not recommend installing "Cool Duals" on
vehicles equipped with a goose neck hitch. The under bed structure
of the goose neck hitch and the driver side tail pipe interfere
with each other. We recommend using a single exhaust system
if a goose neck is installed on the vehicle.
DOES MBRP BUILD STACKS FOR TRUCKS?
- MBRP produces the most extensive range of pick-up truck
stacks under the SMOKERS™ brand. Choose between singles
or duals in 4" diameter pipe to 5". Add on any of
a variety of stacks, from 4" to 8" diameter, Turn
Out, Aussie, Angle Cut or Straight in T-304 mirror polished
stainless steel or black coat we have the stack system to
match your personal sense of style.
