Kooks 3-Inch Stainless Steel Cat-Back Exhaust with OEM Tips for 2012–2021 Jeep Grand Cherokee SRT8 & 2018–2021 Trackhawk 6.4L/6.2L
The Kooks 34104200 3-inch stainless steel cat-back exhaust system delivers the ultimate performance upgrade for 2012–2021 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 25–35 rear-wheel horsepower and 30–45 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.
