  • FAQ's

    • WHAT IS THE DIFFERENCE BETWEEN T409 AND T304 STAINLESS STEEL?

      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 rust 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.

    • WILL I BE ABLE TO KEEP MY SPARE TIRE IN PLACE IF I GET A "COOL DUALS" SYSTEM?

      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).

    • DO 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.

    • WHERE IS THE CLOSEST DEALER TO MY LOCATION?

      You can find the dealer closest to you at our https://mbrpautomotive.com/index.php?page=dealerlocator_adp

    • WILL 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.

    • WHAT 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" to 4" tail pipes while the "Cool Duals" systems use 2.5" tail pipes. The front pipes on the MBRP Sport Truck systems vary from 3" to 3.5" depending on the size of the factory exhaust.

    • WHAT 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".

    • WILL 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. If you have any questions after checking out our catalog or price sheet don't hesitate to call us toll free at (888) 636-7223.

    • WHAT GAUGE IS THE STEEL THAT MBRP USES?

      All of the pipes are made from 14 and 16 gauge tubing.

    • WILL 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.

    • IS THE MIRROR POLISHED DIESEL TIP INCLUDED?

      Tips are included many of our 4" diesel applications (except the PLM, SLM, and performance series). Tips are included in all of our Gas applications (except the Performance series).

    • AT 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.

    • DOES 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.

    • WHAT EXHAUST TIP IS INCLUDED WITH MBRP EXHAUST SYSTEMS?

      Our 4"" Pro, XP, and performance series systems come with a T304 stainless steel single wall angle cut tip T5051. 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 down tail.

    • DO 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.

    • HOW 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.

    • CAN I LEAVE THE CATALYTIC CONVERTER IN?

      Yes, all MBRP exhaust systems are designed to retain the factory catalytic coverter.

    • WHAT 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 mufflers used on our diesel systems is a straight flow through design with either a spiral louver core or a perforated 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 MBRP Ltd. 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 intended.

    • WILL MBRP COOL DUALS™ FIT TO MY TRUCK IF I HAVE GOOSE NECK HITCH?

      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 several universal stack kits in 4" and 5" diameters. Single stack and dual stack kits are available.

    • WHAT DO I NEED TO FILE A WARRANTY CLAIM?

      1) Complete the online warranty registration form. 2)A copy of your sales receipt/proof of purchase indicating part number and date of purchase is required. 3)Photos of any defective parts may be requested

    • DO YOU WARRANTY FOR SOUND?

      Because sound is subjective, we do not warranty for sound. There are usually several ways to adjust the sound of your exhaust kit. Please call MBRP direct to discuss these options.
