American Racing Headers Infiniti QX and Nissan Patrol full exhaust systems provide a significant horsepower increase that really wakes up these popular SUVs. It's power you can feel … along with increased torque and fuel mileage. ARH Infiniti/Nissan headers feature long tube primaries in a variety of sizes; some versions are available with a choice of collector diameters. Complementing the long tube headers are complete exhaust systems including high-efficiency mufflers and tailpipes with double-walled, stainless steel tips. Available with or without catalytic converters and designed to last indefinitely, ARH full exhaust systems provide an aggressive tone, yet they are drone and rasp-free. For added low and midrange torque, V8 systems typically use ARH's true two-into-one, merged, large diameter Y-pipes. Additional features of American Racing Headers Infiniti QX and Nissan Patrol full exhaust systems include: * 100 percent long-lasting 304 stainless steel * 3/8 in. thick laser-cut flanges for a warp-free seal * Hand-ported TIG-welded inlets * Optimized primary tube routing for superior fit and performance * Merge collectors include welded scavenger spikes * Catted systems feature 200 cell, metallic substrate catalytic converters for extreme durability * The only exhaust system you should ever need to buy * All American Racing Headers exhaust systems are for off-road use only
