Sound Made for You
MRT's GMC Sierra cat-back systems make an instant difference from the moment you bolt them on. Our Sierra Deep & Mellow Cat-Back emits a loud, deep rumble that's ideal for city streets or worksite. Those who are ready to run free on the highway or off the beaten path will love the MRT ToughTruck Cat-Back that cranks things up a few more decibels. Both systems have a straight-through muffler and CNC-bent wide mandrel tubing to increase horsepower by maximizing flow.
Want a Sierra axle-back exhaust or a custom system? Give MRT a call. We're always designing new GMC Sierra performance parts, and if you don't see the right kit here, it might be on its way. If not, let us make it for you!
Unmatched Quality for DIYers
MRT is committed to making excellent exhaust systems for backyard mechanics. We inspect each part at least four times and design them for bolt-on installation. You don't even need to own a diagnostic tool to know your vehicle is performing its best. Visit the product pages or stop by the MRT YouTube channel to watch reviews of our exhaust systems and hear them for yourself.
