Make no mistake, these Crawford Z Car Exhaust Headers for the 2003-2006 Nissan 350z are the premier headers available for the VQ35 engine. Nothing comes close to giving you the amount of performance delivered.
Headers are looked upon as an artform. To keep everything of equal length, to introduce long piping (without going too long), and then to make it fit, is one of the most challenging things an engineer can design for a car.
What better way to compliment your ride, that with the largest NA gain available in terms of HP & Torque!
When combined with the plenum and high flow cats, expect a whopping 20hp at peak - and near 40 hp at redline!
