    More Horsepower And Torque. Replace those restrictive stock manifolds with a set of MAC Long Tube Ceramic Headers to improve exhaust flow and increase your Mustang's horsepower and torque. Increases of up to 18 RWHP have been seen when installed with a matching MAC shorty Mid Pipe (see drop down option above).

    Ceramic Coating. These Long Tube Headers are completed in MAC's Polished Ceramic Coating that not only looks great, but reduce under hood temperatures to help increase horsepower and extend the life of the headers. Ceramic Coated headers will long out last both chrome plated and polished headers.

    High Quality Construction. Constructed from 1-5/8" mandrel bent 16 Gauge Steel tubing so there are no kinks to rob you of power, these MAC Performance Long Tube Headers feature 2-1/2" True Fit Collectors that eliminate the need for gaskets which are prone to leak and blow out. These headers are then completed in a ceramic coated finish for good looks and a durable long life.

    Recommended Upgrade.
    To realize the full power potential that these Long Tube Headers have to offer, AmericanMuscle recommends a custom tune with a Mustang Handheld Tuner to reprogram the vehicles computer (ECU) for proper operation.

    These Mac long tube headers are designed to fit the 1999-2004 SVT Cobra and 2003-2004 Mach 1 Mustangs with either a manual or automatic transmission. MAC Performance recommends using a MAC shorty Mid Pipe for the best performance gains.

    Technical Note. This MAC Performance product is not legal for use in emission restrictive states.
