CORSA Performance 21051BLK Sport Cat-Back Exhaust for 2018-2021 Jeep Grand Cherokee Trackhawk 6.2L V8

The CORSA Performance 21051BLK Sport Cat-Back Exhaust is purpose-built for the 2018-2021 Jeep Grand Cherokee Trackhawk equipped with the supercharged 6.2L V8. The 21051BLK delivers a deep, aggressive exhaust note tuned specifically for the Trackhawk platform using CORSA's patented Reflective Sound Cancellation (RSC) Technology, producing a sound that is overall louder than stock and drone-free at highway cruise. This Sport sound level system fits the 2018 Jeep Grand Cherokee Trackhawk, 2019 Jeep Grand Cherokee Trackhawk, 2020 Jeep Grand Cherokee Trackhawk, and 2021 Jeep Grand Cherokee Trackhawk, making it one of the top bolt-on exhaust upgrades for the WK2 Trackhawk. The 21051BLK is manufactured in Berea, Ohio from premium stainless steel, saves 4 lbs over the factory exhaust, and improves exhaust flow by 9 percent. Twin 4.5 inch Black PVD Pro-Series dual-wall slash cut tips fill the factory rear bumper cutouts for an aggressive, purposeful look.

Specifications

Vehicle Fitment

Note: This exhaust system may cause a Check Engine Light due to reduced back pressure. This is a known characteristic of high-flow performance exhaust systems and does not affect engine operation. Vehicles equipped with a factory tow hitch require the tips to be adjusted further out from the rear valance to avoid contact. This system does not fit non-Trackhawk Grand Cherokee models.

Installation Notes

• Bolt-on installation with no welding required
• Estimated installation time: 1 to 2 hours
• Required tools: 3/8 inch drive ratchet, 13mm and 15mm sockets (deep and shallow), 13mm wrench, grommet pullers, torque wrench, penetrating lubricant, safety glasses
• Torque all clamps to 45 ft-lbs using the 15mm socket
• Apply supplied anti-seize lubricant to clamp threads only to prevent seizing
• Vehicles with factory tow hitch: adjust tips further out to prevent contact with hitch
• Detailed printed installation instructions included in every kit

About CORSA Performance RSC Technology

CORSA Performance's patented Reflective Sound Cancellation (RSC) Technology is engineered to solve the problem every performance exhaust owner faces: how to get a loud, aggressive exhaust note without the drone that makes highway miles miserable. Traditional mufflers choke flow to control sound. RSC uses precision-tuned internal chambers to cancel drone-frequency sound waves before they exit the system. The 21051BLK applies this same engineering to the Trackhawk platform, delivering a sound that is unmistakably performance-oriented under full throttle while staying civilized at cruise. CORSA engineers the 21051BLK specifically for the Trackhawk's unique exhaust architecture, not a generic fitment adapted from another platform.

Frequently Asked Questions

What years does the CORSA 21051BLK fit?
The 21051BLK fits all four model years of the WK2 Jeep Grand Cherokee Trackhawk: 2018, 2019, 2020, and 2021. It is designed exclusively for the supercharged 6.2L V8 Trackhawk and does not fit any other Grand Cherokee trim.

What is the difference between the CORSA 21051BLK and the 21052BLK?
Both systems fit the 2018-2021 Grand Cherokee Trackhawk 6.2L and use the same 2.75 inch diameter tubing with twin 4.5 inch Black PVD tips. The 21051BLK is tuned to the Sport sound level, which is louder than stock but quieter than Xtreme at cruise. The 21052BLK is the Xtreme sound level and is substantially louder. CORSA does not recommend pairing the Xtreme system with aftermarket headers.

Will the CORSA 21051BLK fit my Trackhawk if it has the factory tow hitch?
The system can be installed on Trackhawks with a factory tow hitch, but the tips must be adjusted further out from the rear valance to avoid contact. CORSA notes this in their product documentation and installation instructions.

Does the CORSA 21051BLK fit the Grand Cherokee SRT or SRT8?
No. The 21051BLK is engineered exclusively for the supercharged 6.2L Trackhawk. Grand Cherokee SRT and SRT8 models with the naturally aspirated 6.4L HEMI require a different system such as the 14466BLK or 21058BLK.

Does the CORSA 21051BLK require any cutting or welding?
No. The 21051BLK is a direct bolt-on cat-back system that connects to the factory catalytic converter outlets using included Torca clamps. No cutting, welding, or fabrication is required.

Will this exhaust trigger a check engine light on the Trackhawk?
It may. High-flow cat-back systems can reduce back pressure enough to trigger a code on some vehicles. This does not indicate engine damage and is a known characteristic of performance exhaust design on the Trackhawk platform.

What warranty does the CORSA 21051BLK carry?
CORSA backs the 21051BLK with a limited lifetime warranty against defects in materials and workmanship for as long as the original purchaser owns the vehicle, with proof of purchase. Under the Magnuson-Moss Warranty Act, installing this exhaust system cannot void your vehicle's factory warranty unless the manufacturer can prove the part caused a specific failure.

How does the Sport sound level compare to the factory Trackhawk exhaust?
The Sport sound level is overall louder than stock under acceleration with a deeper, more aggressive tone. At highway cruise, RSC Technology keeps the cabin free of drone. Real-world sound clips of the 21051BLK on the Trackhawk are available on CORSA Performance's YouTube channel.

Is the 21051BLK 50-state street legal?
The 21051BLK is a cat-back system that retains all factory catalytic converters, making it compliant with federal emissions equipment requirements in all 50 states. California residents should note the Prop 65 warning below.

How long does installation take on a Jeep Grand Cherokee Trackhawk?
Most installations are completed in 1 to 2 hours with basic hand tools. CORSA includes detailed printed installation instructions and all required hardware in every kit.

Can the CORSA 21051BLK be paired with aftermarket headers or a supercharger pulley upgrade?
The Sport system (21051BLK) can be used alongside other performance modifications. CORSA specifically advises against pairing the Xtreme system (21052BLK) with aftermarket headers, but that restriction does not apply to the Sport sound level 21051BLK.

Where is the CORSA 21051BLK manufactured?
The 21051BLK is manufactured in Berea, Ohio at CORSA Performance's facility at 140 Blaze Industrial Pkwy. Technical assistance is available at 800-486-0999.
