      • Cat-Back Exhaust System
      • T-409 Stainless Steel Tubing
      • Mandrel Bent Tubing
      • High-Flow Muffler
      • Limited Lifetime Warranty
      • Fits 2014-2018 5.3L Silverados


      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.

        Not what I expected!

        Yes, I have a V6. No I did not expect it to sound like a V8. But it sounds like a Honda Civic with an oil can muffler. Did not fit as expected either. Both tail pipes were slanted and one stuck out further than the other. Having new factory exhaust installed next week.

        Sounds great

        Installed in my 2018 Silverado custom. If you don't have a lift and just a Jack you will have to cut the original exhaust. I used an engine hoist to lift the back end of the truck by the trailer hitch and took out the original exhaust in 1 piece. Installed new exhaust piece by piece and it was easy. The only complaint I have is the clamps have spacers in them so no matter how tight I tighten them it seemed it was too loose and they come apart while I was driving. I managed to take out the clamps and took out the spacers (it wasn't easy). Reinstall the clamps and able to tighten and squeeze the pipe and they will never come loose again.

        Best investment

        For the price, this is awesome! Everyone has commented around my town on how nice it sounds. Gives a growl that's not too loud but loud enough to turn heads. I love it!

        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

        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...
