The MBRPARMOR PRO Series is designed and built for the most serious enthusiast who will settle for nothing less than top of the line.

ARMOR PRO Series exhaust systems are backed by a Lifetime Warranty and crafted out of T304 Stainless Steel - the most durable material grade that money can buy. 

The T304 Stainless Steel tubing is easy to clean and maintain. It’s the obvious choice for you if you operate your vehicle in extreme conditions. All of the tubing is mandrel bent for maximum exhaust flow. Mandrel bending ensures no rippling in the bends. The end result is that it gives you more fresh air inside your engine’s cylinders, allowing it to produce more power and improve vehicle performance and longevity.

All of the MBRP series can be found in Cat-Back, Resonator-Back, DPF-Back and Axle-Back configurations in 2.5-inch to 5-inch tubing sizes depending on your vehicle. Many systems offer you the choice of rear, side, or turndown exits as well with an assortment of tips for the ultimate in style and vehicle customization.

  • What exhaust tip is included with MBRP systems that include a tip?

    Tim Hoover | 5/22/2019

    MBRP 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. MBRP  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. MBRP 5" diesel, Performance series and PLM systems do not have a tip included nor do systems with a turn down tail.

  • Will a dual exhaust fit around my hitch?

    Chris Roark | 5/22/2019

    All MBRP 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.

  • Will these MBRP exhaust fit my Dually truck?

    Earl Wilcox | 5/22/2019

    All MBRP 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.

  • Will I have to weld any components to install an MBRP exhaust system?

    Colt Dyer | 5/22/2019

    No - MBRP exhaust systems do not require any welding. In fact, MBRP exhaust systems can be installed using common hand tools.

  • Is there a difference in performance between duals and single exhaust systems?

    Erick Baily | 5/22/2019

    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.


    Donald Daily | 5/22/2019

    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.

  • What is the difference between T304 and T409 Stainless?

    Tyler Fisher | 5/22/2019

    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.
