Corsa Xtreme 2.5" Cat-Back with 4.5" Polished Pro-Series Tips (21187) - 2011-2021 Jeep Grand Cherokee 5.7L V8
Give your 2011-2021 Jeep Grand Cherokee 5.7L V8 a significantly more aggressive exhaust note with the Corsa Xtreme 2.5" Cat-Back Exhaust. Designed for enthusiasts who want maximum sound from their Grand Cherokee, the 21187 delivers an Xtreme exhaust character that measures 20 dB louder than stock under acceleration while also removing 18 pounds compared with the factory exhaust system.
The system features a 2.5" Cat-Back configuration with a dual rear exit and large 4.5" polished Pro-Series exhaust tips. With its combination of aggressive sound, reduced weight, and a clean dual-exit appearance, the Corsa 21187 provides a substantial upgrade for 5.7L HEMI-powered Grand Cherokee models.
Xtreme Sound Level
The Corsa 21187 is configured with Corsa's aggressive Xtreme sound level. Under acceleration, the system produces an exhaust note measured at 20 dB louder than the factory exhaust, creating a substantial change in the sound and personality of the Grand Cherokee's 5.7L V8.
For drivers who want their HEMI-powered Grand Cherokee to have a significantly stronger presence during acceleration, the Xtreme configuration delivers the highest level of aggression offered for this exhaust family.
20 dB Louder Than Stock Under Acceleration
Corsa specifies the Xtreme 21187 at 20 dB louder than the factory exhaust under acceleration. This substantial increase gives the 5.7L V8 a much more pronounced exhaust note when the throttle is opened.
Because of the aggressive Xtreme sound level, Corsa recommends turning off the vehicle's ECO mode for the best driving experience. The 4-cylinder ECO mode may also be tuned out for drivers seeking to avoid the change in exhaust character associated with cylinder deactivation.
18 Pound Weight Savings
In addition to its substantial sound increase, the Corsa 21187 reduces exhaust system weight by 18 pounds compared with the factory configuration. This provides a meaningful weight reduction while upgrading the sound and appearance of the Grand Cherokee.
2.5" Cat-Back Exhaust System
The Corsa 21187 features a complete 2.5" Cat-Back configuration. The system uses a dual rear exit layout, maintaining the performance-oriented appearance expected from the Grand Cherokee's V8 powertrain while replacing the factory exhaust components from the Cat-Back connection point rearward.
The Cat-Back design provides a comprehensive exhaust upgrade rather than simply replacing the rear tips or mufflers, giving owners a complete Corsa system engineered around the 5.7L V8 Grand Cherokee application.
Dual Rear Exit with 4.5" Polished Pro-Series Tips
The 21187 finishes the Grand Cherokee's exhaust with a single large 4.5" polished Pro-Series tip at each rear exit. The dual rear configuration provides a balanced appearance while the oversized polished tips give the rear of the vehicle a more aggressive performance look.
Each Pro-Series exhaust tip features a dual-wall, slash-cut design. The polished finish provides a clean, premium appearance that complements the Grand Cherokee's rear styling while clearly distinguishing the upgraded Corsa exhaust from the factory system.
Designed for the 5.7L V8 Grand Cherokee
The Corsa 21187 is designed for a wide range of 2011-2021 Jeep Grand Cherokee models equipped with the 5.7L V8, including Standard, Laredo, Overland, Overland Summit, and TrailHawk configurations.
Fitment is subject to an important rear tow hook restriction. This exhaust system will not fit vehicles equipped from the factory with a rear tow hook.
