Description

The MBRP Armor Lite 4" Cat-Back Exhaust System S6108P offers a value price without compromising on the quality built into every component. While the seams are a major point of rust through with some budget systems the MBRP Armor Lite (formerly known as the Performance or PLM Series exhaust systems) features fully sealed tubing to help add years to your system.

Built to Perform 
You count on your truck to tow all of your gear to where you want it. With your MBRP performance exhaust you can make that happen with up to 18 HP more horsepower and 28 ft/lb more torque. Give your truck more pulling power and much improved throttle response with an MBRP diesel exhaust system. Our systems are so much more efficient, it will be easy to see what your truck can really 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 2no-weld00 degrees 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 installing this on your truck 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 is just as important. Every MBRP performance exhaust system has been specifically tuned to get the optimal sound from your pickup. With our unmistakable styling, there's no question that you have the hottest exhaust on the road - MBRP.

Really Impressed
Jeff (Palmer, AK) | May 17th, 2025
I don't know how they got this so dang perfect, but this had to be one of the easiest aftermarket product installs I have ever done. Literally, 45 min off with the old and on with the new. Everything lined up, fit, and tightened up as designed. It also sounds good.

Awesome!
Ler (Hawaii) | December 8th, 2023
This system is well made and connections fit perfectly. Definitely purchase the 36” or 42” straight piece to replace the Cat section. Extra clamps are a must. Very happy with the sound even up hills in low. Drone is minimal.

great price on new exhaust
Brandon (Wisconsin) | August 16th, 2021
My 05 cummins had some tired old rusty exhuast. Found this system and the price was real good. I simply removed my old exhaust and slapped this system on in about 1.5 hours( mind you there were a couple breaks to assure proper fluid intake of the beer kind). Overall very happy with it. Sounds just fine and at a price you cant beat.

MBRP 4” Catback system fast and easy
Cagle (Pocola, Ok) | April 13th, 2021
Product shipped quickly even after being on back order. The description was exactly what I received and it sounds great on my 5.9 Cummins. The only real issue I had was a some minor damage to the ends of the pipe but it appeared to be from the original manufacturer not XDP.
