    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.

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

      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...
