    Well-Designed Exhaust System. Affordable but effective, the MBRP Installer Series 3-inch Single Side Exit Cat-Back Exhaust brings the full suite of MBRP's carefully engineered exhaust systems to the table when it comes to improving your 2014-2018 Sierra's performance. Sound is very important with an exhaust system, and the Installer Series Cat-Back delivers a full but mellow exhaust note that is heard as a quiet, pleasant rumble in the cab. The 4.5" polished exhaust tip adds a swanky touch to your truck's styling, while the system causes exhaust gases to gush out rather than building up, loosing the engine's potential to the tune of +1-2 mpg and +5-10% torque and hp. The cooler exhaust temperatures (up to 200° F cooler) also help prevent breakdowns.

    Winning Design. Built with professional attention to detail, the MBRP Installer Series Cat-Back Exhaust features 16-gauge 3-inch piping and an all-welded chambered muffler for top performance. With the exception of the T-304 stainless steel tip, the system is made from aluminized steel that is affordable and backed by 3 year limited warranty. Aluminum silica reinforcement on the seams helps delay that event.

    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.

    Application. The MBRP Installer Series 3-inch Single Side Exit Cat-Back Exhaust is designed to fit with all of the cab and box configurations available for the 2014-2018 GMC Sierra trucks that feature the 5.3L engine.

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

      Sounds Great but fit wasn't quite right

      For starters, I do not have a lift or ramps I can put my truck on so I knew it would be more challenging than the instructions and videos show. In order to remove stock exhaust, I used a sawzaw to cut the pip before the resonator. Took two people but it came out fine. Installing the new exhaust, we hit a snag on one of the pipes that fit over another. The pipe was bent. Looks like it was dropped in the factory or possibly damaged in shipping. Took some pliars and was able to bend it back out. Other than that, no issues. The truck sounds like a truck should. Very pleased with the sound and would recommend. I do hear a small drone around 55-60 especially with the cylinder deactivation but it's not unbearable.

      Okay.

      Sounds great. When I received it though I had to bend dents out of pretty much each piece so they would slide together.

      Exhaust

      I bought this looking for just a little more sound from the truck without drowning out the cabin. Perfect mix ! Nice sound when getting on it but can still hold a conversation inside.

      Best Cat Back I ever installed

      I installed this "installer series" MBRP Cat Back on my 2018 Chevy Silverado with the 5.3. The install was easy.. no issues. I have a short cab standard bed so I had to cut the first stretch of pipe short by following the included instructions. After that everything was a precise fit. The sound is amazing. No drone, just a tuned sounding rumble on the highway. Under acceleration it howls out a nice deep growl and makes the 5.3 sound like a classic American V8. No frills, just straight forward simple exhaust that does exactly what it is supposed to do on a Chevy pick up. Comes with a beautiful polished tip that sets off the install with a nice touch.

      Great exhaust

      Great exhaust. Easy to install. It has a nice rumble when I put my foot to the floor. The hardest part of the install was getting the stock exhaust hangers off.

      Awesome sound Easy Install

      I bought this system because my factory exhaust was bad so instead of replacing with factory I decided to go with MBRP Exhaust system as an upgrade. I have to say that I'm glad I decided to get this exhaust system as it makes my 2014 Chevy truck sound amazing and installation was super easy, it took longer removing the old system vs installing this new one. After all was said and done it took me less than an hour to replace my exhaust system.

      Sounds great

      Hardest part of the whole installation was getting the old system out. Once that was done, the new one took about an hour to install. That included cutting an inch of the over the axle section so the hanger rods would not rub on the shocks. The exhaust tone is great and back pressure is definitely reduced. Interesting how the engine sounds like a lawn tractor when it drops to 4 cylinder mode.

      great sound , not to load .

      Fit perfectly and sounds awesome , put the truck on four ramps and had to jack up the the back a few inches in order to remove the stock exhaust in one piece ,that was the hard part putting the new system together was both fun and easy . I am in my mid fifties but feel like a kid every time i start my truck and hear that sound .

      Great pipes, easy install

      Just like stated its a simple bolt on kit, just undo one bolt and 3 hangers and it pops right on. Sounds great, loud on a cold start but quiets down when warmed up, no excessive drone at highway speeds.

      Very nice!

      "Some cutting may be required", indeed! I used an exhaust cutter to get the old one out, but once that was done, putting the MBRP in was piece of pie. Love the sound and apparent increase in power/efficiency.
