Upgrade the exhaust flow and sound of your Duramax with this simple to install kit from MBRP. Built from only the highest quality aluminized steel and including all of the necessary hangers and clamps, this cat back system will not only deliver the sound you want from your Chevy, but also the added performance, MPG's, and EGT reduction.

Built from heavy duty aluminized steel, MBRP's Armor Lite Series exhaust systems offer 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, this system features fully sealed tubing which adds years to your system. Constructed to the same specifications as their top of the line Armor Pro Series, its backed with a 1 Year Warranty.

Built to Perform - You count on your truck to handle whatever you need it to do. With MBRP Armor Lite exhaust, you can make that happen with up to 18 more horsepower and 28 ft/lb more torque, not to mention lower EGTs (Exhaust Gas Temperatures). 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 muffler-less design 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 degrees Fahrenheit 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 and Style - Performance is one thing, but MBRP believes 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 MBRP, there's no question that you have the hottest performance exhaust on the road - MBRP.

Fantastic Boots!
Size: 8.5, Color: Redwood/Gum 10
Completely satisfied with these boots. True to size, well made, comfortable from the get-go; not break in needed. Waterproof- really. The Red Suede has withstood a nasty winter season & still looks great. Good traction. I like the ankle height which looks good with long, mid length pants & leggings. I love the easy slip on/off aspect..made getting ready for dog walking easy. I 100%recommend!

Definitely worth the price
Size: 6.5, Color: Black/Black
Absolutely love these boots! I originally bought them to wear in NYC in December & they did not disappoint. They were comfortable, cute, durable and worked well in the slush/snow. The traction on the bottom is also nice! They kept me warm with wool socks. I wear them almost daily now. Perfect for everyday. easy to wear with variety of outfits. Good every day shoe.

Snagged a deal
Size: 7, Color: Redwood/Gum 10
I waited and waited to get these boots! I knew I was chancing it, but they went on sale, and I snagged them! I am a size 7, and they fit nicely with socks. a little loose, barefooted, but what psycho wears boots without socks? They are comfortable and really well-made.

Cute, comfortable waterproof boots (a little snug to put on)
Size: 7, Color: Velvet Tan/Gum 2
These are really cute Chelsea-style boots and feel very comfortable once they’re on. The waterproof material is great for wet weather and the sole feels sturdy with good traction. They look stylish enough to wear casually but still feel practical for rainy days. The only downside is they can be a little difficult to put on at first because the opening is somewhat snug, but once they’re on they fit well and feel supportive. Overall they’re a great waterproof boot and I’ve enjoyed wearing them.

Surprisingly great for my wide feet and high instep!
Size: 10.5, Color: Velvet Tan/Gum 2
So thrilled I took a chance on these. Finding boots is impossible for me. I have wide feet, a super high instep, a bunion on one foot, and I wear a hard to find size (10.5). I ordered the 10.5 and 11 in these expecting I might need to size up for width (if I could even get them on). It was a struggle getting the 10.5s on the first time, and once I did they were somewhat uncomfortable on the top of my left foot. But I read that they would relax so decided to give it a go because I need waterproof boots for an upcoming trip and the 11s felt too long. After two days of light wear, they are already breaking in and I have no more discomfort. Getting them on is already easier and they are plenty wide enough and very comfortable to walk in. These are true to size. Super happy and worth a day of mild discomfort to break them in!
