Infiniti QX56 V8 5.6L 2012-2015 Long System




Answering the call for high quality header & exhaust systems for 2010-2015 5.6L V8 Nissan Patrol/Infinity QX56 was a top priority for American Racing Headers. Our newest systems for this application provide up to 40 Rear Wheel HP, which really wakes up this popular SUV. That’s power you can feel along with increased torque and fuel mileage.

ARH Infiniti/Nissan headers are available with either 1-3/4” or 1-7/8” diameter, long tube primaries, each version featuring ARH exclusive TIG Welded 3” merge collectors and scavenger spikes. ARH headers feature 3/8” thick Stainless Steel flanges dressed with hand-ported inlets. Without question, expect a great fit from our headers to match their outstanding performance. Add 40 RWHP to your Patrol or QX56.

Complementing our long tube headers are our three available exhaust system options. (1) a complete system featuring our Pure Thunder Series muffler and tailpipe with Oval Double Walled S/S Tip (2) our Pure Thunder Series muffler working in tandem with the factory resonator (3) or with our 3” Y-pipe ONLY designed to allow you to reuse the factory muffler and resonator (This setup requires mild modification to join both systems).

Our system provides the most aggressive tone yet it is drone and rasp free. Reusing the factory resonator will mellow the tone even further. For HP lovers who require quiet exhaust sound, we strongly recommend reusing the factory catback. For added low and midrange torque, all systems use our true 2 into 1 merged 3” Y-pipe with your choice of ARH 200 cell high flow metallic cats or without. 100% USA made components and assembly - on or off road - our truck systems are designed to last indefinitely and take the fun factor to a whole new level!
