Why CORSA?
The CORSA 14991 Sport Cat-Back Exhaust System surpasses all competitors, offering an unrivaled combination of power, sound, and durability. Here’s why it’s the top choice for your Jeep Grand Cherokee:
Performance Gains: Featuring a 2.5-inch mandrel-bent 304 stainless steel design, this cat-back exhaust boosts exhaust flow by up to 96% compared to stock, delivering +8 horsepower and +12 lb-ft of torque. This enhances your 5.7L HEMI V8’s acceleration and responsiveness, transforming every drive into an exhilarating experience.
Sport Sound Profile: CORSA’s patented Reflective Sound Cancellation® (RSC®) technology produces a bold, aggressive exhaust note with +12 dB under acceleration, while eliminating cabin drone during cruising. The Sport sound level offers a perfect balance of commanding presence and highway comfort, ideal for daily driving and spirited performance.
Lightweight Design: At 13 lbs lighter than the factory exhaust, the 14991 improves your Grand Cherokee’s power-to-weight ratio, enhancing handling and agility for both street and off-road adventures.
Premium Durability: Constructed from 304 stainless steel, this system ensures corrosion resistance and lifelong durability, even in harsh conditions. Handcrafted in the USA, it reflects CORSA’s 25+ years of exhaust expertise.
Sleek Aesthetic: Dual 4.5-inch Polished Pro-Series tips provide a refined, high-performance look that complements the Grand Cherokee’s rugged styling, with a slash-cut, dual-wall design for a factory-like finish.
Hassle-Free Installation: Engineered for a bolt-on fit, the 14991 requires no welding and includes all necessary hardware and instructions, allowing for a quick 30-minute installation.
Included:
- 2.5-Inch Cat-Back Exhaust System: Mandrel-bent 304 stainless steel tubing for optimal flow and durability.
- Dual 4.5-Inch Polished Pro-Series Tips: Dual-wall, slash-cut tips for a refined, aggressive appearance.
