    Aftermarket Improvement. Installing a MBRP XP Series 3-inch Split Side Exit Cat-Back Exhaust on your 2014-2018 GMC Sierra will give it a deeper, bolder exhaust note that's still smooth and agreeable. This MBRP XP Series Cat-Back can also help to produce up to 5-10% more horsepower and torque, with a noticeable increase in throttle response. As an added bonus you may even see a 1-2 mpg increase in fuel economy.

    High Quality. The MBRP XP Series Cat-Back is manufactured from T-409 stainless steel, which will last the lifetime of your truck without rusting through (though it may darken or tarnish). 16-gauge tubing is used for added strength, and the whole system is welded (including the chambered muffler).

    Easy Installation. The installation process of MBRP Cat-Back Exhaust is easy and the exhaust system can be installed with common hand tools. The bolt-on, no weld design provides you with a hassle-free installation process that can be completed in approximately 1-2 hours. Depending on your cab and box size, some cutting to the piping may be required.

    Lifetime Warranty. MBRP Performance provides their XP Series Exhaust with a lifetime warranty against defects in material and workmanship to the original purchaser starting from the date of purchase. The XP Series may develop surface rust over time, which is not covered by this warranty. Some exclusions may apply, please see manufacturer's warranty for complete details.

    Application. The MBRP XP Series 3-inch Split Side Exit Cat-Back Exhaust is designed to fit with all of the cab and box configurations available for the 2014-2018 GMC Sierra's equipped with the 5.3L engine.

            Review from MBRP 3 in. XP Series Dual Exhaust System - Side Exit (14-18 5.3L Silverado 1500)

            Awesome !

            I do a lot of research and I feel like American trucks has a awesome website with install videos. I’m overly pleased with my new exhaust! Came fast, it’s the perfect amount of sounds to get your stock truck sounding like a real truck after an cold air intake upgrade as well! No real loud drone just when you take off you hear it

            Review from MBRP 3 in. XP Series Dual Exhaust System - Side Exit (14-18 5.3L Silverado 1500)

            MBRP 3" XP on 2014 Chevy Silverado

            I was very pleased with the quality of the exhaust system and the look once installed. The tone of the exhaust is very throaty, a little more than I expected as there is a definite drone noise inside the cab. I would also recommend that if your truck is a few years old, you should purchase a new clamp that attaches the catalytic converter to the main extension pipe.
