Our full system provides the most aggressive tone yet it is drone and rasp free. Add 40 RWHP to your QX80 or QX56 with our header and full exhaust, which feature state-of-the-art component engineering. Answering the call for high quality header & exhaust systems for 5.6L V8 Infiniti (2017-Present) 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.
