Each Kooks exhaust system is designed specifically for the engine and vehicle it is built for. Kooks utilizes the firing order of the engine when designing their exhaust tubes. Every system is dyno and race tested to ensure the results are up to Kooks' expectations. This means Kooks can guarantee their exhaust makes the most horsepower and torque in the industry.

Every collector features Kooks' scavenging spike to ensure maximum flow. Laser cut 3/8" thick flanges ensure no warping or bending occurs. Each port is hand ground to make sure they are perfectly smooth so there is no exhaust constriction. Kooks systems are bolt-in and never require any cutting or welding.

All Kooks products are manufactured in a 45,000 square foot state of the art facility located in Statesville, North Carolina.

Are these headers together with a catted Kooks h pipe emission legal in Maryland?

Asked by: dohc97
We don't keep track of the aftermarket part laws in any area, so we'd encourage you to check the list of official approved CARB parts here: http://www.arb.ca.gov/msprog/aftermkt/devices/amquery.php.
