2017- 2020 F150 Raptor MRT Deep & Mellow Axle Back Exhaust

Owners of the 2017-2020 Ford Raptor aren't satisfied with the status quo - otherwise you'd have a boring stock F150. We know how unique the Raptor line is, so we've designed a line of exhaust to enhance your truck's presence as you leave others in the dust - a sound so you can Get Noticed all over again. The Raptor MRT Deep & Mellow Axle Back delivers an on-demand sound that balances a tough growl when you rev up and a refined rumble at idle. On-road or off-road, it will make getting behind the wheel a whole new experience: the Deep & Mellow line is a great option for those looking to enhance their exhaust presence without disturbing neighbors or sacrificing the comfort of the ride. The reasons why you'll love your new MRT Deep & Mellow Axle Back system doesn't stop with the sound: we use mandrel bends and a straight-through muffler design to produce increased exhaust flow. Not only will your truck have a louder, richer exhaust note, but it will also gain noticeable horsepower, torque and fuel economy. It's one of the most cost-effective ways to upgrade your F-150 Raptor and keep it at the head of the pack.

Be a Beast with the Right Exhaust System

Every MRT Ford Raptor Axle Back Exhaust is handcrafted from T304 stainless steel right here in the U.S. This system includes three-inch mandrel bent tubing and dual four-inch double-wall, and reuses the factory exhaust tips. This system is engineered for the best sound to match your vehicle.

The Deep & Mellow Cat Back is quieter than the MRT Tough Truck Cat Back with DMS, but louder than your stock Raptor. It has just enough exhaust presence with elevated sound to Get Noticed, plenty of opportunity to Feel the Performance and is packaged in a design without excessive drone. DIY backyard installation takes about 90 minutes using standard hand tools - you don't even need a tuning. We inspect each system a minimum of four times to ensure quality and back them with a limited lifetime warranty.
