This MRT Street Race Cat Back Exhaust is designed to ensure the supercharged 6.2L HEMI V8 in the 2018-21 Grand Cherokee Trackhawk is felt and heard! The Street Race Cat Back series is the next step up in MRT performance exhausts. It's powerful, aggressive and takes no prisoners wherever you drive. From highways and backroads to off-road trails, our Jeep Trackhawk exhaust upgrade is a sure way to Get Noticed.

Some SUV enthusiasts might think there's no way you can improve on a supercharged small-block HEMI engine. These people have never met the team at MRT! Since 2003, we have developed exhaust systems that dig deep into a vehicle's soul to draw its emotions out. This 2018-21 Trackhawk exhaust is the most complete aftermarket system you can purchase with a design that lifts your vehicle to new heights.

Advanced Performance in a DIY Package

The Trackhawk Cat Back System is handcrafted from three-inch T304 stainless steel for improved corrosion resistance and exhaust gas flow. The result is the biggest and baddest sounding performance exhaust that is always "on." When you smash the gas pedal to the floor, this impressive exhaust somehow turns it up another notch, letting people know that you're ready to burn rubber and take names.

Not only is it loud and proud, but you'll also Feel the Performance from the increased horsepower and better fuel efficiency. This system re-uses the factory tip to preserve the stock exhaust presentation while surprising everyone with a deep performance rumble in all driving conditions. If someone sees your Trackhawk back and thinks they're about to hear a regular, boring SUV when you turn the key, they'll be in for quite a surprise! Let us know if you would like a custom exhaust tip that offers a different look.

It's time to truly experience the power of the HEMI V8 under the hood of this SUV beast! Our Jeep Grand Cherokee Trackhawk Cat Back is designed, engineered and manufactured in the U.S. with a limited lifetime warranty. Any backyard mechanic can install it themselves. All required hardware and instructions are included, and the only tool you need is a 15mm socket wrench. You don't even need to tune the engine.
