This unit is designed for Mitsubishi Galant 2.4L (2378 cc) L4 models from 2004 through 2012 that use the 4G69/2.4L engine. Confirm fit by matching your year, engine size, and OEM/reference numbers listed.
The listed OEM/reference numbers include 327-59391, 674-836, MN156409, MN15670, 099-1824, and 01386. Compare these to your factory manifold/catalyst number to confirm compatibility.
This is intended as a direct-fit exhaust manifold with dual catalytic converters for the specified Mitsubishi Galant 2.4L models. However, always verify OEM/reference numbers and vehicle emissions tag before purchase.
O2 sensors are not listed as included. The product includes the manifold/catalyst assembly, gaskets, and hardware shown. In most cases you will reuse your factory oxygen sensors; check the listing or seller for confirmation.
The listing states that necessary gaskets and hardware are included as shown in the product images. If you need exact quantities or specific fasteners, confirm with the seller before buying.
No. This item is NOT C.A.R.B. (California Air Resources Board) approved and therefore cannot be shipped to California. It also cannot be installed on California-emissions-equipped vehicles in New York.
The product includes a 2-year warranty against manufacturing defects. For warranty claims, keep your order information and contact the seller with photos and a description of the defect.
The high-flow design is intended to improve exhaust flow and increase oxygen availability to the engine, which can result in modest gains in power and throttle response. Gains depend on vehicle condition and other modifications.
The product is described as fully tested under extreme heat conditions for heat resistance and long-life use. Specific materials are not listed; contact the seller for detailed metallurgy or coating information if required.
Professional installation is recommended because installation involves exhaust disassembly, torqueing to spec, and correct O2 sensor handling. If you install it yourself, use proper gaskets, torque bolts to manufacturer specs, and check for leaks.
Verify your vehicle’s year, engine (2.4L 2378 cc / 4G69), VIN engine code (if present), and the OEM/reference numbers on your current manifold/catalyst. Also check the emissions label under the hood for California-emissions designations.
The primary restrictions noted are California (no shipment) and New York regarding California-emissions-equipped vehicles. Local/regional emissions laws can vary, so confirm with local authorities or the seller if you have concerns.
Document the issue with photos, keep all packaging, and contact the seller or marketplace immediately with your order number. For warranty-covered manufacturing defects, follow the seller’s warranty claim process.
Service life depends on driving conditions, fuel quality, and maintenance. The product is tested for heat resistance and durability, and comes with a 2-year manufacturer defect warranty, but individual lifespan will vary.
