Built from 16 gauge T409 stainless steel our SLM Series performance exhaust systems offer a value price without compromising on the quality built into every component. Featuring a two-piece tail wee replaced the muffler with an MBRP muffler delete pipe to provide you with the ultimate in free flow exhaust.Constructed to the same specifications as our top of the line Pro Series we back this line with a 5 Year Warranty.Built to PerformYou count on your truck to handle whatever you need it to do. With MBRP you can make that happen with the horsepower, torque and lower EGTs that only a wide open, free flowing performance exhaust system can provide. More pulling power, improved throttle response, greater fuel efficiency, with an MBRP diesel performance exhaust you will be amazed at what your truck can do.Minimize BackpressureThe secret to getting more out of your diesel engine is to give it lots of cool, clean air. The only way that you can get fresh air in is to get the hot air out. Thanks to MBRP muffler delete, the fully mandrel bent tubing and minimal bend degree angles, your MBRP performance system gets exhaust out fast. Drop exhaust gas temperature by up to 200 °F and set the stage for all the performance you want. An MBRP performance exhaust system is the starting point to getting the most from cold air intakes, programmers, modules and downloaders.Easy InstallationMBRP systems are as much fun to install as to drive with on your truck. Bolt-on, no weld design makes installation a no hassle one and a half to two hour project. Everything is direct fit to the OEM hangers and you get all the clamps and parts you will need, all in one box, no matter what configuration of truck you have.Sound & StylePerformance is one thing but at MBRP we believe that appearance and sound are just as important. Every MBRP performance exhaust system has been specifically tuned to get the optimal sound from your pickup. With our stamped logo on the tip and our unmistakable styling, there's no question that you have the hottest performance exhaust on the road - MBRP.
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.
