Infiniti G35 DE headers

3-07 350z and g35 DE headers

This 350Z / G35 Performance Headers are an evolution of the original VQ Performance Headers, re-engineered using the most advanced CAD techniques and manufacturing processes.

These headers are constructed with 1 3/4″ 304 stainless steel primaries, feeding into a cast merge collector (also stainless 304). Unlike fabricated merge collectors, cast collectors offer better consistency in manufacturing, resulting in improved flow characteristics and scavenge effect. A merge spike is welded inside the collector, making the transition from the primary tube to the collector as seamless as possible. Like the collector, the cylinder head flange is also manufactured from precision castings and features a complete 12-hole bolt pattern. The cast cylinder head flange was designed to transition from the oval exhaust port shape to the round primary tube without the need to crush the primary tube, promoting great flow from the moment exhaust gasses enter the header. Every primary tube is carefully measured to ensure equal length with a tolerance of just a fraction of a millimeter. This precision allows exhaust pulses to hit the collector in perfect timing, creating a vacuum that pulls in fresh air and fuel during the intake stroke – a critical feature for maximizing the “scavenge” effect in high-revving performance engines. These headers are still in perfect condition with less than 3k mileage on them.

These Headers are made of thick T-304 Stainless Steel and are mandrel-bent to form and fit your particular application with the best performance results possible while the thick flanges and strong welds prevent cracking and offer long-lasting durability. These Headers and Turbo Manifolds help your engine maximize its performance by allowing the exhaust gasses to flow more efficiently to gain power and performance. (NOTE: For off-road use only, not intended for use on public

These headers will fit on an Infiniti G35 2004 – 2008 & Nissan 350z Z33 G37 Models.
