MBRP's PLM Series features Aluminized Steel 4" & 5" Downpipe-Back
and Turbo-Back exhaust systems with a Muffler Delete Pipe and No Tip. This creates
the lightest system available, which makes it perfect for recreational activities
like Closed Course Racing, Sled Pulling, Diesel Drags and more. 2-yr Mfr Warranty.
Yes, the kits for the 08 trucks fit all cab and bed configurations.
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.
They do not make the NO MUFFLER exhaust for the Excursions. Correct part number for a 01 excursion will be a C6204AL for aluminized and S6204409 for Stainless, then you could couple that with a muffler delete pipe.
