Designed specifically for 2003-2006 models equipped with the 3.5L V6 engine, these high-performance G35 exhaust headers are crafted from T304 stainless steel with a mirror-polished finish, offering superior durability, heat resistance, and style.

The Engineering: Why Upgrade to Aftermarket G35/350z Headers?

When modifying your vehicle, comparing aftermarket g35 or 350z headers to a restrictive stock manifold is essential. Factory cast-iron parts force exhaust gases to collide, choking your engine’s performance. Here is how FLASHARK solves this:

• The Scavenging Effect: Our precisely tuned primary runners ensure that exhaust pulses do not interfere with each other. This creates a vacuum that literally “pulls” the exhaust gases out of the next cylinder, allowing your V6 to breathe easier.
• Mandrel-Bent Tubing: Unlike cheap crush-bent pipes that restrict flow at the curves, our design gives each engine cylinder its own dedicated, smooth tube, eliminating gas collision.
• Premium Material: Factory manifolds trap heat and rust. Our headers are constructed from high-grade stainless steel for vastly superior thermal efficiency and corrosion resistance.

Installation Notes:

These headers are designed as a direct bolt-on replacement for your factory manifolds. They feature pre-welded O2 sensor bungs for a straightforward swap. However, due to the tight engine bay space in the VQ35DE chassis, we highly recommend having them installed by a professional mechanic.
