      MagnaFlow Sound. The sound you get from a MagnaFlow exhaust system has become so famous that it's now used as an adjective. "MagnaFlow Sound" is a deep, throaty tone with a mellow undercurrent that no other system can provide. The Street Series gives you that quintessential growling rumble while cutting out the natural harshness.

      Added Horsepower. Whether you have a Sierra or a Silverado, the OEM exhaust system is creating back pressure and restricting flow for the sake of emissions. The MagnaFlow Street Series Performance Exhaust system does away with those shackles, giving you unfettered exhaust flow and increasing your torque, horsepower and fuel economy.

      Resilient Construction. MagnaFlow produces the Street Series right here in America using 100% 409 stainless steel tubing. Every curve is also mandrel-bent to keep the interior surface as smooth and unrestricted as humanly possible.

      Quick Bolt-On Install. Installing your new MagnaFlow Street Series Exhaust System will require basic hand tools — no welding whatsoever.

      Application. MagnaFlow Street Series Performance Exhaust is a direct fit for 5.3L 2014 - 2018 Chevy Silverados and Sierra 1500s.

        Awesome exhaust for the 5.3

        This has one of the cleanest sounding and deepest exhaust notes for the 5.3 engine. I researched for a few months listening to hundreds of sound clips and while there are other great sounding exhaust i always came back to this as my standard..."but was it better than the magnaflow?" Now, anyone that has looked up anything involving exhaust knows of the v 4 drone issues cant avoid reading something on it so it should not come as a surprise. If you don't plan on getting the tuner (400 ish but def worth it) or other device that is just for cutting out AFM (200 ish) off then you may want to consider something a little more subtle so its not as noticeable to you. This is the deepest tone you can get while being moderately loud so expect it to be noticeable when you hit v 4 mode simple as that. Lots of good clips all over you tube of cab sounds, drone etc so. I have had flow-masters and magnaflow as well as a few others in the past and i always got more compliments on the magnaflows, they just sound so dang good!

        Bad choice

        This exhaust is VERY LOUD. Deep and mellow, but LOUD. It sounds fine when accelerating in v8 mode but when the truck switches into v4 mode the exhaust note sounds like a constant loud subwoofer note that vibrates everything inside the cab. I can hear bolts rattling under the dash. This will force me to purchase an expensive tuner to turn v4 mode off. Not recommended.

      thinking about this setup for my truck...question however, will running boards be in the way? Meaning, will running boards impact the look of the exhaust system?

      • This exhaust setup should not interfere with the running boards on your truck.

      I have a 2018 High Country with running boards that automatically go in and out when you open and shut the doors. Will that be a problem with this exhaust?
