    Power Builder. Every bit of extra power and performance you can add to your 2014-2018 Silverado makes getting the job done faster and easier, or increases the possibilities for fun, and the MBRP XP Series Split Rear Exit 3-inch Cat-Back Exhaust adds several useful things to your pickup. The mandrel-bent tubing greatly increases exhaust outflow, cooling the exhaust by 200° F and clearing fumes so a stronger airflow occurs into the engine. This translates to an increase in fuel mileage, horsepower and torque gains, and lessened chances of engine breakdown. Your Silverado also gains a mellow but strong exhaust note, along with the brash styling of two polished T-304 stainless tips.

    Reliable Quality. The MBRP XP Series Cat-Back is manufactured out of T-409 stainless steel, which is proof against corrosion but will dim and discolor over time. The T-304 tips, however, will remain bright permanently. The tubing is 16-gauge 3” steel, and the seams are reinforced at points of high stress. This system is made for bolt-on application and fits the factory hangers without welding, using the included hardware. Depending on your cab and box configuration, some cutting to the piping may be required.

    Application. This MBRP XP Series Split Rear Exit 3-inch Cat-Back Exhaust is designed to fit on all cab and box configurations available for the 2014-2018 Chevrolet Silverado models equipped with the 4.3L engine.

        will this work with the fuel management system without sounding like a putt, putt machine when only 4 cylinders are firing?

        • The MBRP 3 in. XP Series Dual Exhaust System is a standard exhaust and will not change any part of its configuration when your truck goes in to active fuel management/cylinder cut off mode.

            Noise level

            Wasn't nearly as loud as i would have thought, no noise through the entire power band, needed professional cutting and shaping to fit 2016 silverado

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

            Very Nice!

            It took a little longer than I expected after reading multiple reviews on the exhaust. I was not supposed to have to cut my extension pipe for it to fit on my truck but after examining the set up I ended up cutting a small part of the extension pipe to better fit everything. Love the sound and performance of it. Mild drone in the V4 mode on my 2014 Silverado but will likely adjust and get rid of that with a tuner in the future. Mpg went up as well paired with the KandN cold air intake.

            Sounds and Looks Great

            Just had this system installed on my 14 Sierra All Terrain and it has a Great Sound and I also Added 5in tips which make it sound even better... NOW ONE NOTE, it is NOT a full 3in system!!!!!!! From the muffler back to the bumper the pipes are 21/2in, NOT 3in... Aside from that, it seems to be the best bang for the buck that I have found so I'll see how it works out... I'm a MAGNAFLOW user, but this shinny muffler seems to have that same mellow sound, unlike that other flow hollow beer can sounding muffler that seems to be so popular...Also with my KandN cold air intake, when you put your foot into it wow, makes you want to do it all the time...
