The Kooks 34104200 3-inch stainless steel cat-back exhaust system delivers the ultimate performance upgrade for 2012 and 2021 Jeep Grand Cherokee SRT8 (6.4L) and Trackhawk (6.2L supercharged) models, replacing factory piping from the catalytic converters back with mandrel-bent T304 stainless tubing and high-flow straight-through mufflers that unlock dyno-proven gains of 25 and 35 rear-wheel horsepower and 30 and 45 lb-ft of torque while retaining factory quad tips and Active Exhaust valve function for seamless integration.
Handcrafted from T304 aircraft-quality stainless steel with full TIG welds and polished 4-inch double-wall tips, this system supports over 1,000 HP without drone, providing an aggressive supercharged roar in Track mode and refined quietness in Normal/Touring modes. The bolt-on design uses factory hangers and clamps for easy installation with no cutting or welding required.
For SRT8 and Trackhawk owners demanding championship-level power and sound with factory appearance, the Kooks 34104200 cat-back is the complete solution for street, track, or off-road dominance.
