Exhaust Header VS Manifold, which is the better choice?
3000GT & Stealth headers are made from lightweight stainless steel, in contrast to the thicker iron used in exhaust manifolds. Headers are longer and more efficient, helping to reduce back pressure and improve exhaust flow, which results in more horsepower and better engine performance.
Upgrading to exhaust headers not only enhances engine performance but also improves exhaust sound. FLASHARK's headers are designed for a direct bolt-on installation—no modifications needed, making them an easy and effective upgrade for your 1991-1999 Mitsubishi 3000GT or Dodge Stealth.
Fitment & Compatibility
| Brand | Model | Year Range | Full Compatible Specs |
|---|---|---|---|
| Mitsubishi | 3000GT / JDM GTO | 1991-1999 | Z16A Chassis; Factory-Equipped 3.0L 6G72 DOHC Naturally Aspirated (N/A) V6 Engine |
| Dodge | Stealth | 1991-1996 | Factory-Equipped 3.0L 6G72 DOHC Naturally Aspirated (N/A) V6 Engine |
Q1: What vehicles are these exhaust headers compatible with?
A1: These performance exhaust headers are specifically designed for the 1991-1999 Mitsubishi 3000GT (including the JDM GTO Z16A chassis) and the 1991-1996 Dodge Stealth.
Q2: Will these fit my 3000GT VR4 or Stealth R/T Twin Turbo?
A2: No. These headers are strictly engineered for the naturally aspirated (N/A) 3.0L 6G72 DOHC V6 engines. They are NOT compatible with VR4, Twin Turbo, or turbocharged models due to completely different exhaust routing and flange designs.
Q3: My Dodge Stealth has a SOHC 3.0L engine. Will these headers work?
A3: No, these are designed exclusively for the Dual Overhead Cam (DOHC) 24-valve 3.0L 6G72 engines. The cylinder head exhaust ports on the Single Overhead Cam (SOHC) 12-valve engines are different, so the flanges will not match up.
Q4: What performance gains can I expect from this 3000GT exhaust header upgrade?
A4: Upgrading from the restrictive factory cast-iron exhaust manifolds to our mandrel-bent tubular headers significantly reduces exhaust backpressure. This improvement in exhaust scavenging velocity frees up trapped horsepower, increases mid-range torque, and greatly improves overall engine responsiveness.
Q5: How will these headers change the exhaust sound of my 300L V6?
A5: Removing the thick iron manifolds and installing these lightweight stainless steel headers will unlock a much deeper, throatier, and more aggressive exhaust note. It gives your 3000GT or Stealth that true, unrestrictive sports car sound it deserves.
Q6: Are these 6g72 non-turbo headers a direct bolt-on, or is fabrication required?
A6: While designed for a standard fit, the 3000GT/Stealth engine bay is notoriously tight. Based on tuner feedback, achieving a perfect, rattle-free fitment may require minor fabrication. This can include slightly shaving the rear motor mount bracket for clearance, gently tweaking the oil dipstick tube, and making minor adjustments to the connection pipe between the front and rear banks.
Q7: What material are these Dodge Stealth / Mitsubishi 3000GT headers made of?
A7: They are constructed from high-quality, lightweight stainless steel, offering superior heat resistance and durability compared to mild steel. They are finished with a sleek mirror polish to enhance the look of your engine bay.
Q8: Where is the O2 sensor bung located on these headers?
A8: These headers feature a pre-welded single O2 sensor bung. Depending on your specific year and emissions equipment setup (OBD1 vs OBD2), you may need to extend your O2 sensor wiring harness slightly or relocate the bung at an exhaust shop to ensure optimal sensor readings and prevent check engine lights.
Q9: Why should I choose Flashark stainless headers over OEM iron manifolds?
A9: OEM iron manifolds are heavy, retain excessive heat, and feature poor internal aerodynamics that choke exhaust flow. Our tubular stainless steel headers are significantly lighter, run cooler, and utilize individual primary tubes that merge smoothly to maximize flow efficiency.
Q10: Are exhaust gaskets and mounting hardware included?
A10: Yes, the header kit comes with standard replacement gaskets and basic mounting hardware. However, for high-heat performance applications, many veteran 3000GT tuners prefer to reuse original OEM Mitsubishi multi-layer steel gaskets or upgrade to premium aftermarket copper gaskets for the ultimate leak-proof seal.
Q11: Will this header kit pass state emissions testing?
A11: These headers are sold as an off-road performance upgrade. Because they alter the factory exhaust flow and may delete or relocate factory catalytic converter positions depending on your exhaust setup, they may not be legal for street use in states with strict emissions laws (like California's CARB regulations). Please check your local laws before purchasing.
