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.

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 full 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!

If you are asking yourself if you should install an aftermarket performance exhaust or if they are worth the cost maybe we can help allay your fears in that respect. First of all, race headers are undoubtedly one of the simplest changes you can make that will generate an improvement in the way your engine performs because they are primarily a bolt-on application. They function by making it simpler for your engine to work exhaust gases out of the cylinders and they accomplish this by affording each cylinder with its individual exhaust pipe of equal lengths resulting in each cylinder’s exhaust gas being given the opportunity of arriving in the collector evenly with an absence of back pressure and consequently improving your engine’s power.
