    Boost Your Sound. Growling aggressively and throatily when accelerating and subsiding to a pleasant rumble when cruising, the MBRP XP Series 3-inch Split Rear Exit Cat-Back Exhaust gives your 2014-2018 Silverado an exciting new exhaust note. The same features that make this system sound great - mandrel-bent tubing and a high-flow muffler - also make it an exciting performance exhaust. Under optimal conditions, the XP Series Cat-Back dishes out an extra +5% to +10% horsepower and torque by bleeding off backpressure and lowering exhaust gas temperature (EGT) by up to 200° F. To top it off, this cat-back is made from T-409 stainless to last your truck's lifetime.

    High Endurance Part. MBRP builds its XP Series Cat-Back Exhaust as a middle option between aluminized and T-304 - the T-409 won't rust through, but may discolor with surface oxidation over the years. The tip is mirror-polished T-304 stainless steel, which will stay bright and clean looking. The tubing is 3" diameter and mandrel-bent for smooth flow, with thick 16-gauge walls for extra sturdiness. This is a bolt-on system that comes with all hardware, clamps, and a limited lifetime warranty.

    Application. This MBRP XP Series 3 in. Split Rear Exit Cat-Back Exhaust is designed to fit on all cab and box configurations available for the 2014-2018 5.3L Silverados.

      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...
