Rugged and dependable our Armor Plus Series is made of T409 stainless steel. It's designed and built to stand up to the harshest road conditions. We are so sure that our Armor Plus has what it takes that we have given it an amazing Lifetime warranty. That is absolutely the best warranty for a T409 system in the industry. Budget-friendly entry into stainless steel exhaust systems.
MBRP XP Series Exhaust System Features:
Exhaust kits will come with clamps and hangers.
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.
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.
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.
No - MBRP exhaust systems do not require any welding. In fact, MBRP exhaust systems can be installed using common hand tools.
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.
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.
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.
