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.
