    Product Description

    Kinetix has taken the simple test pipe and high flow cat pipe to the next level.  Each Kinetix high flow cat pipe is designed to be a direct replacement for the ultra restrictive factory piece to improve the breathability of the motor and increase horsepower and torque.  Kinetix uses a special "spun" catalytic converter design that is completely stainless and built strong to last even the toughest conditions.  These catalytic converter pipes will also not throw a check engine light and are street legal in 49 states (Not legal in California.  Check your local smog laws).

    Kinetix Catalytic Converter pipes feature:

    • New design with more clearance for easier installation
    • "spun" catalytic converter for higher flow and added strength
    • Street legal in 48 states (not California or New York - check your local laws)
    • Retains factory o2 sensor locations and will not throw a check engine light
    • Comes complete with bolts, washers and lock nuts
