      Fresh Power Unleashed. A restrictive factory exhaust keeps your 2014-2018 5.3L Silverado from reaching its true potential. However, MBRP's Installer Series Single Side Exit 3-inch Cat-Back helps to provide relief and free up power so you can put it to good use. Accelerating the waste gases out through 3" mandrel-bent piping, the Installer Cat-Back improves front-to-back exhaust flow enabling better performance with an increase in both horsepower and torque. Your Silverado will even sound better, with a rich, mellow rumble instead of the OE exhaust note.

      Affordable Aluminized Steel. The aluminized steel of the MBRP Installer Series 3-inch Cat-Back fends off rust while keeping the system price low, and MBRP added several features to boost durability. The seams are thickly coated in aluminum silica so rust can't start there, while the piping is made from burly 16-gauge steel. Arriving ready to bolt on to the factory hangers with provided clamps and hardware, the Cat-Back sports a glistening T-304 polished stainless steel 4" tip with the MBRP logo.

      Painless Installation Process. The MBRP Installer Series 3 in. Cat-Back Single Side Exit Exhaust System is easy to install since it simply bolts onto your truck’s OEM hangers. Depending on your cab and box configuration, some cutting of the piping may be required.

      Application. This MBRP Installer Series Single Side Exit 3-inch Cat-Back Exhaust is designed to fit on all cab and box configurations available for the 2014-2018 5.3L Chevrolet Silverado 1500 models with an one-piece driveshaft.

        Sounds good and easy to install for the price. Did take a little over a hour to install because I did have to do a little cutting to fit a crew cab short bed.

        Simple install

        Did the install myself. Took a little over an hour because i did not really have help but with a second person it would have taken half the time. The video showing how to install it helps alot with the install process. Sounds great at a great price

        Nice tone...

        Installed on my 2018 Sierra std cab with 8' bed. Installation was super easy. OEM rubber hangers and one clamp (which I broke...) must be reuse. This exhaust gives the truck a really nice tone; it's not super loud but just right... My truck no longer sounds like a sewing machine.

        Great value

        A super easy install, the only downside is you may have to cut the factory exhaust out unless you have a lift. Otherwise good tone and not overpowering.

        I was a little skeptical at first because of how good the price was and with me having a 4.3 Silverado BUT this exhaust is actually really awesome, it sounds great for the price I recommend it

        Nice exhuast

        Its a nice cheaper exhuast bolt on system. Its not loud but it has a decent growl on cold start and when you punch the gas. I have 2 little ones in the truck with me and didnt want anything too loud. This is perfect. Cant hardly hear it inside the cabin until you punch on it and even then its not loud inside the cabin. I have 2 conplaints about the system I wish the tip was longer and i wish they would send a new factory exhuast clamp that they want you to re use. My was rusted and not reusable so i had to go order a new one. But the system lined up perfect with factory hanger locations. All in all a good cheaper system. I did it myself. Cut the old one out and installed the new one in about an hour.

        Great bang for the buck!

        It’s perfect for the owner who just wants a little extra noise from the pipes and it’s super easy to install. No drone whatsoever.

        Great value

        Added this with a cold air intake with a spacer. From what I read it's the same one in regards to sound and performance just a cheaper metal. Ok, works for me. Doing the install FIRST if your doing it in the driveway and have little helpers you must drop the spare and jack up the rear at the hitch so you dont ruin everyone's day. It took me longer than it should. Once I did that the whole thing came right out. Second, this is a cheaper metal attaching to the catalytic keep that in mind. I think the only difference between this and a 1k cat back system is the sound. Your not going to get monster gains driving to and from work or cruising the strip.

      I live in New England where they salt the roads in the winter how will this hold up against salt? And why is the black version of this $200 more? Is it because the black ones painted for the New England salt?

      • This stainless steel has been known to hold up well to conditions such as those. The black version is a black aluminized steel, which costs more.

      Will there be any issues when my 2015 5.3L Sierra kicks down to 4 cylinders? I’ve read that some after market cat back exhaust system cause issues when the trucks kick down to 4 cal and a programming change is necessary.

      Will this throw a code after installation?

      • Since the emission components are not being changed or modified this would not produce a code on your truck.
