Nissan Xterra Headers (WD22) 2000-2004

Increase your Xterras engine performance! Replacing your factory exhaust manifolds with performance exhaust headers, will increase the efficiency of your engine therefore increasing horsepower. This is achieved by building headers with individual, large radius bent, exhaust tubes from each exhaust port to accelerate the flow of the exhaust gasses from your engine. This will increase the efficiency of your motor giving increased horsepower and gas mileage. Headers are also a great alternative to using the expensive factory manifolds on the Xterra being that the factory manifolds are prone to cracking & leaking.
