American Racing Headers Infiniti QX and Nissan Patrol Headers

American Racing Headers Infiniti QX and Nissan Patrol headers add significant horsepower along with increased torque and fuel mileage. They feature long tube primaries in a variety of diameters; some applications also offer a choice of collector sizes. For added low and midrange torque, most V8 systems use ARH's true two-into-one, merged, large diameter Y-pipes, either with or without high-flow cats. ARH Infiniti QX and Nissan Patrol full exhaust systems are designed to last indefinitely.

Available in a choice of styles, ARH QX/Patrol long systems allow you the choice of reusing factory mufflers and resonators or attaching to aftermarket cat-back exhausts with a simple mark and cut (no welding required). Short systems typically require minor fabrication to adapt to the midsections of either original equipment or aftermarket exhausts. For horsepower lovers who require a quiet exhaust, ARH strongly recommends reusing OE factory cat-back systems and resonators.
