Upgrade your VQ35DE engine with the KSP Exhaust Manifold Header, designed for 2003-2006 Infiniti G35 / FX35 and Nissan 350Z Z33. Featuring precision TIG-welded stainless steel tubing, 1-5/8″ primaries, and a 2.5″ collector, it improves exhaust flow for noticeable horsepower and torque gains. The shorty 3-1 direct-bolt-on design ensures perfect fitment, durable sealing, and a deeper, more aggressive exhaust tone—ideal for both street and performance builds.
