MBRP's Pro Series is the best performance exhaust system that money can buy. It is a series designed and built for the serious enthusiast who will settle for nothing less. Constructed from T304 stainless steel it delivers you optimal durability that keeps on looking its best. Easy to clean and maintain this is the product of choice for owners of lifted vehicles, show trucks or who operate in severe environments.
Built to Perform You count on your truck to handle whatever you need it to do. With MBRP performance exhaust you can make that happen with up to 18 more horsepower and 28 ft/lb more torque not to mention lower EGTs. 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 Backpressure The 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. From the spiral louvered high flow muffler to the fully mandrel bent tubing to 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 Installation MBRP 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 & Style Performance 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 new 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 Exhaust Features:
Note: All Crew & Extended Cabs applies to GM 2500HD/3500HD Pickups. This system is not designed for use on Cab & Chassis models.
Yes, the sound will change some.
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.
