Kooks 3" GREEN Catted Connection Pipes for 2009 and 2024 Dodge/Ram 1500 5.7L HEMI
The Kooks 35103202 3-inch GREEN catted connection pipes complete the exhaust upgrade on 2009 and 2024 Dodge/Ram 1500 trucks with the 5.7L HEMI V8, 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 750 HP from tunes or cams without sacrificing ground clearance or daily drivability. The direct bolt-on design preserves the Ram’s refined V8 soundtrack with a deeper, more aggressive tone at wide-open throttle and zero drone at cruise.
For Ram 1500 owners pairing Kooks headers with stock exhaust, the 35103202 GREEN catted connection pipes are the essential emissions-legal link that maximizes HEMI performance with work-truck reliability.

Will these headers void my factory powertrain warranty?
Under the Magnuson-Moss Warranty Act, a manufacturer cannot void your vehicle warranty simply because you installed an aftermarket part unless they prove the component directly caused the failure. Consult your dealer for specifics on your situation. -
