The Kooks 3-inch GREEN catted connection pipes complete the exhaust upgrade on 2015 and 2023 Dodge Charger/Challenger Hellcat (6.2L supercharged) and 2021 and 2023 Jeep Grand Cherokee Trackhawk (6.4L) models, linking Kooks long tube headers directly to the factory mid-pipe for seamless integration that maintains 49-state emissions compliance while adding 20 and 30 rear-wheel horsepower and 25 and 35 lb-ft of torque through high-flow 300-cell metallic substrate GREEN catalytic converters and mandrel-bent tubing.
Handcrafted from T304 aircraft-quality stainless steel with 3/8-inch laser-cut flanges and full TIG welds, these pipes ensure zero leaks under extreme heat and support over 1,000 HP from tunes or cams without sacrificing ground clearance or daily drivability. The direct bolt-on design preserves the Hellcat/Trackhawk's ferocious supercharged soundtrack with a deeper, more aggressive tone at wide-open throttle and zero drone at cruise.
For Hellcat and Trackhawk owners pairing Kooks headers with stock exhaust, the 34103301 GREEN catted connection pipes are the essential emissions-legal link that maximizes supercharged performance with proven reliability.
California Proposition 65: Contains chemicals known to the State of California to cause cancer or reproductive harm.
Warranty: Limited lifetime on stainless construction and 25,000 miles on catalytic converters to original purchaser.
