Nissan 370Z Headers

These 370z headers were designed to increase horsepower more then any other headers on the market.  We have increased our primary runner size to 1 3/4″ to promote exhaust flow on your 3.7L engine.  We have worked in conjunction with some race teams around the country to come up with our runner size and length.  We have seen as much as 30 whp gains with these headers!
