Why Upgrade Your VQ35DE Headers?
Stock manifolds are built for emissions and cost—not performance:
- Restrictive airflow
- Heavy cast design
- Limited power potential
These headers fix that by:
- Improving exhaust flow efficiency
- Reducing backpressure
- Enhancing engine performance and response
Translation: more flow = more power + quicker revs.
Features:
- 100% brand new, Never been tried or installed.
- Made of High Quality T304 Stainless Steel Material
- TIG welded CNC machine flange.
Vehicle Fitment
Compatible with:
- Nissan 350Z (Z33) 2003–2006
- Infiniti G35 2003–2007 (3.5L VQ35DE)
(Designed for VQ35DE engines—does NOT fit HR models.)

Reduces overall engine weight slightly. - Performance-Oriented Layout
Designed to maximize airflow and efficiency. - Direct Replacement Design
Replaces factory exhaust manifolds.
Durable Materials: Crafted from High Stainless steel for longevity.
Precision Design: Optimizes gas flow, minimizing turbulence and backpressure for better engine breathing.
Heat Management: Efficiently dissipates heat, reducing thermal stress and prolonging component life.
What It Does Best
- Improves exhaust flow
- Increases throttle response
- Enhances horsepower potential
- Produces a louder, more aggressive exhaust note
Sound Profile (Brace Yourself)
- More aggressive and raw tone
- Noticeably louder than stock
- Classic VQ “character”… just amplified
If you hated the sound before—you’ll hate it louder.
If you loved it—you’re welcome.
Performance Expectations
- Gains when paired with intake, exhaust, and tune
- Better throttle response
- Improved high-RPM breathing
This is a key supporting mod, not a standalone miracle.
Emissions Compliance: Supports modern emission control systems, reducing harmful pollutants.
What It Won’t Do
Let’s stay honest:
- Won’t add massive power alone
- May trigger check engine light without proper setup
- Not emissions compliant in some regions
This is for performance—not passing smog inspections.
Who Is This For?
- 350Z and G35 performance builders
- VQ enthusiasts chasing better airflow
- Anyone upgrading beyond stock bolt-ons
Corrosion Resistance: Fabricated using special processes to ensure resistance against corrosion and rust, further enhancing durability and longevity.
For 2003 – 2006 Nissan 350Z Z33, 2003 – 2007 Infiniti G35,3.5L VQ35DE
Installation Notes
- Professional installation strongly recommended
- May require O2 sensor extensions
- Gaskets and hardware recommended
- Tune recommended for best results
(Pro tip: Header installs on VQs are not “fun”—plan accordingly.)
Why Upgrade 350Z G35 VQ35DE stainless exhaust headers?
Because this is one of the most effective airflow upgrades you can do before going forced induction.
Final Verdict
The Stainless Steel Performance Exhaust Headers for 350Z & G35 are a solid upgrade for unlocking better airflow, improved response, and a more aggressive exhaust tone.
More flow. More sound. More attitude.
