The Kooks Headers and Exhaust long-tube headers are designed to provide clearance and finish off your swap with a clean look. Not to mention, the additional power. Kits are engineered to fit the RPM Extreme and Motech LS-Jeep-Swap kits.

Kooks Headers and Exhaust LS-Swap Jeep Wrangler JK kits will work with other LS conversion kits, but may require additional parts and fabrication. Depending on your application, cat-back systems and headers/connections-only are also available. The headers feature 3-inch female swivel seal connections, for additional flexibility when building custom exhaust or using the Kooks Headers and Exhaust kit. 

Kits are available with high-flow race catalytic converters or the patented GREENCATS. The ultra-high performance GREENCATS are designed to lower emissions and can withstand up to 900 hp and 1500 degrees of exhaust gas temperature. GREENCATS come with a two-year limited warranty and race catalytic converters include a one-year limited warranty. Non-catalytic converter connections, designed for racing applications, are also available.

Features

• The complete kit provides easy installation
• Additional clearance for tight-fitting LS engines
• Extensive R&D invested in system 
• Available in three y-pipe options

Please note, GREENCATS are highly recommended for any forced-induction applications, and the use of high-flow race catalytic converters on forced-induction applications will void Kooks Headers and Exhaust catalytic-converter warranty.

The necessary installation hardware is provided in kits, including header gaskets, clamps and Stage 8 locking bolts (where applicable).
