Exhaust Cat-Back - 2.5in Dual Rear Exit

The CORSA PERFORMANCE Exhaust Cat-Back 2.5-inch Dual Rear Exit system is a sport-tuned cat-back exhaust designed specifically for the 2014–2021 Jeep Grand Cherokee Summit Edition equipped with the 5.7L Mopar V8 engine. This stainless steel performance exhaust replaces the factory restrictive piping from the catalytic converter rearward, delivering improved engine breathing, enhanced throttle response, and a more aggressive exhaust note characteristic of high-performance V8 platforms. The dual 4-inch black pro-series exit tips provide a professional appearance while optimizing scavenging efficiency through matched pipe diameter and exit velocity tuning.

The 2.5-inch primary pipe diameter represents an engineering balance for the 5.7L V8—large enough to minimize backpressure and exhaust gas velocity losses, yet sized to preserve scavenging pulses that optimize midrange torque delivery. Stainless steel construction resists corrosion from road salt and moisture exposure, extending the system's service life compared to mild steel alternatives. The dual rear exit configuration distributes exhaust flow symmetrically, improving weight distribution and providing visual balance consistent with the Grand Cherokee's aesthetic. Black pro-series tips maintain a refined appearance on premium trim levels while withstanding thermal cycling and oxidation.

This cat-back exhaust is engineered for owners of late-model Grand Cherokee Summit editions seeking measurable power gains, reduced turbocharger lag response, and a more assertive exhaust soundtrack without sacrificing drivability or emissions compliance. Installation requires no welding or modifications to the factory fuel system, suspension, or engine management. Typical gains include 15–25 horsepower and proportional torque increases across the RPM band, with the most noticeable improvement in the 3,000–6,000 RPM range where highway passing power is most relevant. The system maintains OEM-equivalent fitment and hangers, making it suitable for daily-driven vehicles that see both city streets and highway use.

Cat-back exhaust systems represent the entry point for V8 performance modification, offering the highest return-on-investment in terms of power, sound, and installation simplicity. CORSA PERFORMANCE is known within the aftermarket for engineering exhausts that balance measurable performance with OEM-quality fit and finish, making this system a trusted choice for Grand Cherokee owners upgrading from factory equipment.
